摘要: A current sensing regulator operates in a switching mode of regulation between two sensed current levels in a free-running operation, or between one of the current levels and an intermediate level in a fixed-frequency synchronization operation. The sensed current levels at which switching occurs are set through a command signal, and a comparator controls switching at the set current levels or at the occurrence of synchronization pulses.

摘要: A quasi-resonant DC to DC converter having zero-current and zero-voltage switching includes a transformer with primary and secondary windings, and periodic switching means connected in series with the primary winding. The converter further includes an input capacitor parallel to the transformer's primary winding and an output capacitor parallel to the secondary winding. The topology of the converter is determined by selecting an input capacitor having a capacitance much lower than the output capacitor, by selecting the resonance period of a circuit including the input capacitor and the overall series inductance of the transformer to be shorter than the ON period of the periodic switching means, and by selecting the resonance period of a circuit including the overall parasitic capacitance, referred to the primary side of the transformer and the periodic switching means, and the magnetizing inductance of the transformer to be shorter than the OFF period of the periodic switching means.
