On the principle and application of motorcycle rectifier

There is a very important electrical device on motorcycle, which supplies stable charging voltage for locomotive battery. This is voltage stabilizing rectifier, which is called "silicon rectifier" rectification, which is to change AC voltage into DC voltage. Voltage stabilization is to stabilize the output voltage of generator within the specified range, so as to make the battery charge reasonably and the lamp stable brightness; The devices that realize these two functions are called voltage stabilizing rectifiers. The voltage stabilizing rectifiers of motorcycles have been experienced several stages from birth to now. However, until now, most motorcycles still use the clipped short circuit voltage regulator with technical defects, which waste n-more energy with the development of Electronic Science and technology New technology and new element devices are constantly appearing. A new generation of switching voltage regulator rectifier has been successfully researched and manufactured and has been put into use
People are beginning to get familiar with and use it; It can replace the short circuit voltage regulator rectifier completely without long trust. Before the rectifier tube is found, the motorcycle can only adopt complex exciting DC generator and use mechanical voltage regulation method; It is to adjust the exciting current with a replacement. After the discovery of a simple rectifier diode of the mechanical switch voltage regulating circuit, people try to adopt a simpler exciting alternator and adopt mechanical voltage regulation; Then gradually replace mechanical voltage regulation with electronic voltage regulation. That is why the pressure regulating mode used in automobiles at this time why the early motorcycles should use the excitation alternator with complex layout instead of the permanent magnet alternator with simple and smart layout and extremely low obstruction rate? Because the magnetic field of permanent magnet alternator is fixed with coil, the output voltage and frequency are proportional to the speed of the actuator. The voltage range is wide, so it can not be adjusted from the inside by the key point of adjusting the magnitude of exciting current as the exciting alternator. Therefore, the technical premise of stabilizing voltage can not be realized even if the voltage is sent out, However, because of the simple layout of low-power permanent magnet alternator and less obstruction rate, it was widely used in the first rectifier of permanent magnet alternator on motorcycle without voltage stabilizing effect
There are only four rectifiers, namely full wave rectification. It relies on the battery storage capacity to realize the stable voltage (such as XF250) the alternating current through the end diode bridge rectifier from the generator can directly charge the battery. The charging voltage is the output voltage of the generator. With the great change of speed, the voltage and current are far more than the charging voltage and current that the battery is OK; Because the unique voltage stabilizing performance of the battery, the voltage can be stabilized in the suitable range, but the voltage stabilization is at the cost of the battery life. Although the preset life of the battery is three years, it will be damaged in the operation of the driving machine in one year. If the battery circuit is disconnected, the peak voltage of the generator is not received by the battery.
Some electrical appliances will be avoided from burning down. Over time, the voltage of the battery will be lost gradually, and the voltage will gradually increase. It is easy to burn down some electrical appliances. Due to the overcharge of full wave charging, half wave charging occurs. That is, only one diode rectifier is short of power at night due to half wave charging, so that the headlight can only be directly supplied by the generator AC, For example, there are problems in the early half wave charging of Suzuki A100 and Honda CG125: when driving in the daytime, the battery is still overcharged, so there is a discharge resistance connected on the lighting line, which will release the over charge resistance from fever to avoid the battery from being damaged in advance (it is also not necessary to use the battery to make it easy to charge); Driving at night, the headlight is dim at low speed. With the change of driving speed of the driving machine, the lighting validity is not ideal, and the battery can not be satisfied. With the development of Electronic Science and technology, the early rectifying regulator of electronic rectifier voltage regulator adopts parallel voltage stabilization, which is also a short circuit voltage reduction of 12 v. when the output voltage is higher than 15V, the thyristor is on, The input over current thyristor is grounded, and the output voltage of generator will not rise any more;
When the load power consumption causes the output voltage to drop, when the output voltage is lower than 15V, the thyristor will supply the load with the full input current. So repeatedly, the voltage is basically connected to the 15V pendulum. This short-circuit voltage stabilizing mode can improve the voltage stabilizing performance of permanent magnet alternator at the time, which makes the performance of the motorcycle advance very quickly, The speed of the driving machine can be increased at will without any consideration of the output voltage; Whether it is the life of the battery or the lighting brightness, it has been controlled. The external validity is satisfactory. The electronic rectifier regulator can be divided into two kinds of full wave and half wave voltage regulator, which can simultaneously cut the positive and negative half waves to supply power to the whole vehicle and battery, and the energy is abundant, So it is necessary to implement DC lighting (such as fxd12 5, qj12 5, Suzuki king, etc.) half wave rectifier voltage regulator as the automobile, which is used to cut the negative half wave to achieve the purpose of voltage stabilization. The output positive half wave is used to charge the battery. The power supply capacity of the voltage regulator is poor, and it cannot be used for DC lighting.
Only AC lighting mode (such as Haomai 12th Five, Jialing 70, and AX100) with light brightness changing with speed can be used. However, some batteries are not easy to use damaged motorcycles, whether it is AC power supply or DC power supply. The power of generator used is basically the same. Only the connection mode and rectifier used are different. If the AC power supply is changed to DC power supply, the power supply of the generator is basically the same, Only need to change a rectifier and change the route, some vehicles have a large power generation. The modified switched stabilized voltage half wave rectifier is used. The idle light is also very bright. Therefore, it is unnecessary to change the DC. So, it is necessary to emphasize the utility of the detection line on the full wave voltage regulator rectifier: this detection line is connected to the gate and locked out line, When the light is turned on at night, which is used to detect the voltage value on the route, because of the loss on the route, the battery voltage is different from the line voltage. When the line voltage is lower than 15V, the rectifier voltage regulator automatically increases the voltage stabilizing value, so that the line voltage will be maintained at the beginning and end of the line. It is considered comprehensively from the preset point of view, but in fact, some batteries are too high due to the line voltage drop, The fault of detection results in the high charging voltage and damage.
The cost will also be increased; But its advantage is: the policy motive also has the power transmission to the battery in idle state (the personal concept: since it is a serial switch circuit or the output voltage of the actuator is increased, the rectifier and voltage stabilizing circuit can be simplified and the idle speed of the policy motive is more stable). Although I am currently researching and manufacturing the second intelligent charger for the electric oil dual hybrid vehicle, But the most practical method in the motorcycle industry is to realize the first simple and simple voltage switching rectifier as soon as possible. As long as the battery does not exceed the limited charge, the life of the battery can be extended by many. The direct current power supply is also expected to be used for the lamps. For the pan Bo car friends, the battery can only extend the life of half a year, It is almost as much as the cost of energy saving of tens of yuan a year, and the fuel can be used for lambs to run hundreds of kilometers more.
