Abstract

Insertion of a DC-DC converter between the automobile battery and electrical loads is proposed. This allows gradual conversion to higher battery voltage, regulation of DC distribution voltage, and multiple distribution voltage levels. Switching loss arising from parasitic inductances is a serious problem in this application. The nonlinear resonant switch can remove this source of loss, achieving zero current switching without sacrificing conduction loss of MOSFET switch utilization. A low-voltage high-current nonlinear resonant switch converter operating at 700 kHz and producing 600 W is described
