Abstract

In a two-quadrant soft-switching (TQSS) converter, there are no switches available for current boosting because it uses diodes in the current return path. Therefore, a new control-timing scheme is proposed in this TQSS converter with only one auxiliary branch to achieve near zero-voltage switching under all load-conditions. In order to validate the proposed converter, computer simulations were conducted. With the merits of simplicity and flexibility, the proposed TQSS converter shows excellent performance and potential for various industry applications including switched reluctance motor (SRM) drives, high-frequency-high-voltage choppers, magnet drivers, and magnetic resonance imaging (MRI) system applications.
