Abstract : A pulse width modulated DC-to-DC converter circuit is disclosed having a novel means for permitting each of the switching transistor duty cycles to exceed 50% without the occurrence of current spikes at the input winding of the output transformer. These current spikes result when both switching transistors are on when each of the transistors switch operating states at an instantaneous point in time. As a result, a wide range of input power source voltages can be utilized for a given output voltage thereby resulting in a wide range of voltage regulation. This result is achieved by utilization of an energy storage choke between the battery means and the input winding of the output transformer. Whenever there exists an instantaneous current spike, the choke absorbs the spike. (Author)
