Abstract

Current control technology has rapidly developed as the increasingly popular application of power electronic equipment in power systems. Nonlinear current control technology has better control effects on the nonlinear structure of the inverter, so it has important research value. Considering that traditional ramptime current control cannot limit the peak of the current error between inverting current and reference current, a limiting module is added in the improved ramptime current controller. In this paper, the peak of the current error is limited so that the device can be protected while the quasi-fixed-frequency control can be achieved simultaneously. The simulation is accomplished in Matlab to verify the feasibility of improved ramptime current control strategy, which proves that improved control methods can realize accurate current tracking in the single-phase inverter.
