1. Harmonic disturbance
The rectifier circuit will produce harmonic current, which produces a voltage drop on the impedance of the power supply system, resulting in distortion of the voltage wave pattern, and the voltage of this distortion constitutes a disturbance on many appearances, and the common voltage distortion is the flattening of the top of the sine wave. When the harmonic current is constant, the voltage distortion becomes more serious in the case of a weak power supply, and the characteristic of this disturbance is that it will cause disturbance to the equipment that uses the same power grid, and has nothing to do with the separation between the equipment and the inverter.
2. Radio frequency conduction emission disturbance
Because the load voltage is pulse-shaped, the current drawn by the inverter from the power grid is also pulse-shaped, and this pulse current contains a large number of high-frequency components, constituting radio frequency disturbance, which is characterized by the disturbance that will cause disturbance to the appearance of the same power grid, and has nothing to do with the interval between the appearance and the inverter.
3. Radio frequency radiation disturbance
RF radiation disturbs the input and output cables from the LS inverter. When there is a radio frequency disturbance current on the input and output cables of the inverter, because the cable is equivalent to an antenna, electromagnetic wave radiation will inevitably be generated, resulting in radiation disturbance. The PWM voltage transmitted on the output cable of the inverter also contains abundant high-frequency components, which will generate electromagnetic wave radiation and constitute radiation disturbance. Radiated disturbance is characterized by the fact that when other electronic devices approach the inverter, the disturbance becomes severe.
