Abstract

This circuit enables the switching of a line voltage into a ferrite transformer T by alternatively switching K1/K4 or K2/K3 at a high frequency (e.g., 30 KHz) so that the flux is bidirectional. Each switch K1/K4 is a dual switch working with both polarities. (Image Omitted) For each switch, Tp is on and TN is off when VP-VN>O, and Tp is off while TN is on when VP-VN
