Control of a Parallel Resonant Inverter

In this article we propose a combination of generalized proportional integral control and sliding mode implementation, through a /spl Delta/ - /spl Sigma/ modulator, for the solution of an output feedback trajectory tracking problem defined on a single phase parallel resonant inverter achieving a DC to AC power conversion. The proposed controller design approach is robust with respect to sudden constant load variations and it only requires the measurement of the output voltage of the inverter. The main features of the proposed control system is evaluated through computer simulations.
