Abstract
The present invention discloses a high-voltage electric field low-temperature plasma cold sterilization system circuit and apparatus, and belongs to the field of frequency converter power source circuit technologies. The present invention including a power source module, a voltage/current/power adjustment module, a switch module, and a transformer module. The power source module includes a single-phase frequency converter and a first-stage inductance. An inductance is connected in series between the output end of the frequency converter and a voltage regulator, to play a role of a reactor, harmonic components in sine pulse width modulation waves outputted by the frequency converter are effectively restrained, and spectrum is expanded, so that a harmonic current entering the voltage adjustment module is stable, and heat losses of the voltage adjustment module are reduced to prevent burnout
