Why Can't A Frequency Converter Be Used As A Power Supply?

Aug 22, 2018

The entire circuit of the inverter power supply is composed of alternating current, alternating current and filtering, etc., so the voltage and current waveforms it outputs are pure sine waves, very close to the ideal ac power supply. It can export the voltage and frequency of the power grid of any country in the world. The frequency converter is composed of alternating current and alternating current (modulated wave) and other circuits. The waveform of its output voltage is the square wave of pulse, and there are many harmonic components. The voltage and frequency change in proportion at the same time, and cannot be adjusted separately, which does not meet the requirements of ac power supply. In principle can not do the use of power supply, generally only used in three-phase asynchronous motor speed.
