Dynamic performance of an APWM resonant inverter for high frequency AC power distribution systems

In this paper, the feedforward and feedback control loops are designed for the asymmetrical pulse-width-modulated (APWM) resonant inverter to achieve fast transient response for the application in high frequency AC power distribution systems. In the proposed control scheme, the modulated integral control acts as a feedforward loop and provides pre-regulation for the feedback loop. As a result, the APWM resonant inverter has fast transient response against the line and load variation. Simulation and experimental results are presented to prove the dynamic performance of the APWM resonant inverter.
