The inverter compressor controller is mainly composed of a microcomputer microcontroller and peripheral components. And ordinary microcomputer air conditioning outdoor control circuit board is not much different. It also includes a temperature detection circuit, a current detection circuit, a power supply circuit, a protection circuit, an inverter drive circuit, and a communication circuit. The variable frequency controller can generate a corresponding control signal according to the indoor and outdoor functions and the temperature detection signal, so that the on state of the power transistor enables the inverter to output a three-phase AC voltage of a predetermined frequency. The inverter controller is an important part of the inverter air conditioner circuit. It is mainly used to control the opening of the outdoor electronic expansion valve, the inverter conduction, defrosting, and the outdoor fan speed.

The maintenance of the inverter compressor controller is basically the same as that of the outdoor control circuit board of the ordinary cabinet. For details, please refer to the outdoor control circuit board maintenance of the cabinet. However, the inverter controller also has its own characteristics, for example, the driving signal provided to the inverter output is different from the ordinary driving signal (I. e., high level or low level). Therefore, if the output of the inverter controller is always low or high during maintenance, the circuit is not normal.

The inverter compressor controller is mainly composed of inductors and capacitors. Its main function is to absorb various interference signals in the power grid, restrain the electromagnetic interference of the electrical controller itself to the power grid, and prevent overvoltage.

The inductor and capacitor of the circuit are connected in series in the AC power supply, that is, the inductor and capacitor are used to generate back electromotive force when the compressor is started, so as to prevent the starting current from changing too much, thereby protecting the rectifier and the power transistor from damage.

The indoor module BAC02B is used to communicate with the outdoor module BACO1, and then transmits the user's setting mode, setting temperature and room temperature to the outdoor unit, and receives the operation status from the outdoor unit.

The compressor controller is a device that automatically loads and unloads the compressor to keep the pipe network pressure within the settable limits.

After a power failure, the directory runs automatically.

The inverter compressor controller is equipped with a sensor. If the measured value of a sensor exceeds the set shutdown standard, the compressor will stop running, and the shutdown alarm signal will be displayed on the compressor controller.

The inverter compressor controller can automatically load and unload the compressor to keep the pressure of the pipe network within the set limit. Several settable values need to be considered, such as unloading and loading pressures, short downtime and number of motor starts.

The inverter compressor controller will stop running the compressor whenever possible to reduce power consumption, and automatically restart the compressor when the pressure drops. If the expected unloading time is too short, the compressor will run continuously to prevent the downtime from being too short.

The inverter compressor controller has the function of automatically restarting the compressor when the voltage is restored after power failure. This function can be activated or closed according to the needs of customers.

At present, all compressor controllers are equipped with a control panel, which can display the current and temperature of the compressor host through the LCD display. pressure, operating time and working state, etc. The operator can control the compressor through the control panel, set the control parameters, and display the required parameters. Illegal operations are prohibited.
