摘要： A power feeding apparatus which is used in a high-frequency heater or the like, is further power-converted by a transformer after the power provided by the power supply such as commercial power supply or the like has been converted into the high-frequency power by a transducer including a semiconductor, feeds the converted power into the load having the unidirectional electrical current characteristics of magnetron or the like. The generating voltage is dropped so that the stable power may be fed without the corona discharge and the acr discharge to be caused, the insulating withstand voltage between the windings of the transformer, the pulling of the wirings, and the insulating withstand voltage may be reduced.

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： This inverter circuit includes two switching elements which are turned alternately ON and OFF, and a first primary winding connected in series between these switching elements, and also includes an output transformer having a secondary winding for obtaining an output voltage. This inverter circuit also includes a first voltage source and a second voltage source. The first voltage source applies a voltage to the first switching element via the first primary winding. And the second voltage source applies a voltage to the second switching element via the second primary winding. This inverter circuit also includes a regeneration snubber circuit for regenerating charge accumulated in a snubber capacitor. The regeneration snubber circuit includes a regeneration circuit including a voltage boost section which converts the primary side voltage of the output transformer to a predetermined voltage, which it outputs.

摘要： An inductive load drive device is disclosed comprising: a monitor circuit that inputs the drive-side terminal voltage of an inductive load (ZL) and, when a drive current of the inductive load (ZL) is cut off or rapidly decreased, outputs an operation confirmation signal by detecting a surge current generated by self-induction of the inductive load (ZL), wherein the monitor circuit outputs a confirmation signal that detects a surge produced when a large current flowing in the load due to high voltage applied in an initial period of drive of the load (ZL) is rapidly decreased, wherein in order to prevent confusion of the surge with a surge produced when the load drive is terminated, the operating confirmation signal is masked by using a control signal indicative of the termination of drive of the inductive load.

摘要： A transformer (201) includes a push-pull winding wherein each side is divided at its centerpoint and leads are brought out for switching devices (204) or rectifiers (205) so that leads from the source voltage and to the loads are separate from the switching devices and rectifiers which may be located for optimal circuit topology. The winding may be of coaxial wire for improved performance and floating capacitors (208) or floating snubbers (206) may cross couple the terminals where the switches (204) and rectifiers (205) are connected.
