In this paper, a modified zero-voltage-switching pulsewidth-modulation inverter with a digital-signal-processor-based proportional–integral–derivative (PID)-like fuzzy controller (PIDFC) is implemented. The switches of the inverter can achieve a soft-switching feature that can largely reduce switching losses and improve the converting efficiency. In order for the online control of the proposed dc–ac inverter to be feasible, a fuzzy control is designed to be a PID-like fuzzy mechanism with the complexity significantly reduced. From the results, it is shown that the PIDFC can not only stabilize the output at 110 V rms but can also improve the performance when the system load has been changed from 600 to 100 $\Omega$. Comparing with a traditional PID controller, the responding speed can be improved by 75% in the simulation, and the speed can still be improved by 35% in the practice experiment.
