The input AC is converted into DC voltage through rectifier circuit and flat wave circuit, then through the INVERTER DC voltage into different width of the pulse voltage (called pulse width modulation voltage, PWM) . Using this PWM voltage to drive the motor, you can adjust the motor torque and speed. This principle leads to the following three kinds of electromagnetic interference: 1. Harmonic interference rectifier circuit will produce harmonic current, this harmonic current in the impedance of the power supply system voltage drop, resulting in voltage waveform distortion, this distorted voltage can interfere with many electronic devices (because most of them can only work under sine wave voltage) . The common distortion is that the top of the sine wave is flattened. When the harmonic current is constant, the voltage distortion is more serious when the power supply is weak. This kind of disturbance will disturb the equipment using the same power network, and it is independent of the distance between the equipment and the converter 2. RF conducted emission interference because the load voltage is pulse-like, so the inverter draws current from the power grid is also pulse-like, this pulse current contains a large number of high-frequency components, the formation of RF interference, the characteristic of the interference is that it will disturb the equipment using the same power grid
