PT Control Strategy Based on Differential Boost Inverter

This article studies the pulse train (PT) control strategy based on differential boost inverter. Differential Boost inverter has the function of achieving single stage boost and inverter, but due to its nonlinear characteristics, it is difficult to model and design simple and accurate controllers using traditional linear control strategies. PT control is based on a voltage and current dual loop, which adjusts the output voltage by outputting appropriate high-power control pulse PH and low-power control pulse PL, achieving fast and accurate control of nonlinear inverters.
