Abstract :
A version of the resonant pole inverter includes a saturating inductor and a current feedback winding. The standard resonant pole inverter becomes a special case of this inverter and design degrees of freedom increase significantly. The focus is on the control of this type of inverter, and the switching frequency variation and dynamic response are addressed. It is shown that a saturating inductor can improve the stability of the switching frequency while very fast dynamic response is possible in the case of an inductive load. Experimental results are presented.<>
