Zusammenfassung:	A pulse width modulated DC-to-DC boost converter circuit in which switching losses are minimized. The circuit operates at a constant frequency and in continuous mode (at a constant current). Turn-on losses are minimized by causing the parasitic intrinsic capacitance of the main switching device to be discharged before the switching device is switched to the conducting state, and reducing reverse recovery current from the output rectifier of the circuit when the output rectifier turns off. Turn-off losses in the switching device are minimized by causing a condition of zero volts across the switching device at turn-off.
