[0025] Comparative example:

[0026] The application adds a relay compared with the traditional one, the relay is a bypass switch of the breakthrough prevention resistor (NTC), and can make the working current pass through the breakthrough prevention resistor (NTC) for a long time, and the entire DC FFU controller is protected against surge;

[0027] The application adds a relay, a terminal and a driving circuit compared with the traditional one. When these components are not installed, the motor cannot be stopped for over-temperature protection in case of motor overheating.

[0028] The application adds a 7815 stabilizing triode compared with the traditional one. The +15V stabilizing voltage is mainly used for IPM power supply. The power supply capacity and stability of the 7815 stabilizing triode are much higher than those of the stabilizing triode, which can make the DC FFU controller run more stably.

[0029] The application adds a 7805 stabilizing triode compared with the traditional one. The +5V is used for RS485 power supply. The TO-220 package of L7805 has higher power supply capacity and stability than the SOT-89 package of 78L05, which can make the RS485 communication more stable.

[0030] The application adds a communication circuit compared with the traditional one. LTV356-T is a general optocoupler with low transmission rate, but it can normally and stably communicate at a baud rate of 9600, but there may be unstable communication at 19200. 6N137 is a high-speed optocoupler with a data rate of 10Mb / s, which has been verified to have no problem when used at a baud rate of more than 19200.

[0031] The application adds a choke compared with the traditional one. The choke is installed to prevent electromagnetic interference generated by the motor from affecting the controller. To ensure that the DC FFU can run stably for a long time, a choke is installed on the new optimized DC controller.

[0032] The application adds a heat sink compared with the traditional one. The heat-conducting silicone grease makes it easier to combine the components with the heat sink, and the heat-conducting silicone grease is tightly attached to the heat sink, which makes it easier to conduct the generated heat. The heat conduction capacity of the aluminum alloy plate is better than that of the pure aluminum plate.

[0036] Power filter: Its function is actually bidirectional, which can effectively prevent electromagnetic interference from the outside world from entering the equipment through the power line, and can also block the electromagnetic disturbance generated by the equipment itself from entering the power grid through the power line, and transmitted to other sensitive equipment. Adding power filter greatly improves the anti-interference ability of the product, and also greatly reduces the interference to other equipment.

[0037] Rectifier bridge: Its function is to convert the AC power of the power grid into pulsating DC voltage.

[0038] PFC boost component: combined with control algorithm, improve the stable bus voltage, while the input current control, make it with the input voltage waveform synchronization, improve power factor, reduce the harmonic content, so as to improve the utilization of electric power.

[0039] IPM driver: combined with control algorithm, produce amplitude, frequency can be changed sine current, drive motor operation.

[0040] FFU execution controller: from 485 communication receives external instruction, executes control algorithm (FOC), provides PWM control signal for IPM module control motor operation. In the control motor, detect the relevant signal of control circuit, if the signal is abnormal, execute protection mechanism. Again through 485 communication, send relevant data to host computer.
