摘要： A circuit comprises a power tank, a pair of transformers and multiple loads. The power tank converts a DC input voltage to an AC voltage. The pair of transformers comprise a pair of primary windings and a pair of secondary windings and transform the intermediate AC voltage to an output AC voltage. The pair of primary windings are coupled to the power tank for receiving the intermediate AC voltage, and the pair of secondary windings provide the output AC voltage. The loads are coupled to the pair of secondary windings for receiving the output AC voltage. The pair of secondary windings are serially coupled to each other through the series-coupled loads to achieve current balance among the loads.

摘要： In a DC-DC converter equipped with an operation mode (standby operation mode) which is only for reducing consumption power in a light load state such as at the time of a start-up, there is an output power dive detecting circuit disposed which outputs a result of a comparison of an upper limit output voltage E1, which is higher a predetermined voltage than a target output voltage E0, with an output DC voltage Vo. The DC-DC converter does not enter the standby operation mode when the output DC voltage Vo is higher than the upper limit output voltage E1, which greatly improves a response speed at which the output DC voltage Vo efficiently reaches the target output voltage E0.

摘要： The sequencer employs a variable current source, a Schmidt trigger circuit, a one-shot, a pair of master-slave flip-flops and logic gates to provide pulses for operating a multiple switching regulator. A logic gate disables the sequencer to prevent the generation of pulses while a portion of the switching regulator is delivering current to an output terminal and thereby prevents possible damage to the switching regulator.

摘要： A full wave inverter circuit having a DC input voltage and an AC output voltage of controlled fundamental frequency. Constant amplitude voltage pulses are applied to a center tapped primary winding of a transformer to generate alternating current pulses in a center tapped secondary winding of the transformer. The center tapped secondary winding is connected to a converter to convert the alternating current pulses into unidirectional positive pulses and alternately into unidirectional negative pulses which are applied to an electrical load through a filter. The width and repetition of the constant amplitude voltage pulses is varied so that the integral of the converted alternating current pulses constitutes a lower frequency alternating current output waveform.

A pair of conventional diodes connected across the commutating capacitors limit the reverse voltage across these capacitors and limit the operating currents and voltages in the other elements of the switching regulator.
