ABSTRACT:
A novel resonant DC-to-DC converter has a source of direct current which is switched through a primary inductor, or the primary winding of a transformer in a primary circuit, to provide energy to an LC tank circuit. The sinusoidal, AC tank voltage is impressed upon an output winding that feeds an output smoothing inductor through a full wave rectifier. The resultant direct current output is made availabe to a load. A unidirectional switch operates in response to a switch control to perform the switching in the primary circuit at near zero current conditions. The switch control opens the unidirectional switch to end the current pulse. The length of the current pulse is proportional to the magnitude of the load.
