Abstract

Abstract

Inverter power is the important equipment to realize reactivity control of nuclear reactor. The existing inverter power can not keep the actual DC operating current constant when the power supply fluctuates and the operating frequency changes. In order to make the actual DC operating current constant, this paper studies a DC feedback control technology of inverter power, which takes the actual DC operating current as feedback, uses proportional-integral regulator for feedback control, and uses space vector pulse width modulation (SVPWM) algorithm to modulate the given operating frequency and regulator output into pulse width modulation (PWM) signals that drive the inverter bridge. The feasibility of this method is demonstrated by simulation, and a feedback inverter power is developed. The effectiveness of this technology is verified by experiments.
