摘要： The invention aims at putting a single ended resonance type converter capable of obtaining a ZVS operation over an overall corresponding load region to practical use. A switching power supply circuit includes a primary side switching converter of a class-E resonance type, and a choke coil of a primary side series resonance circuit of the class-E resonance type converter is used as a primary winding of an insulating converter transformer. With this structure, a choke coil winding to be inserted into an input line of a DC input voltage is arranged between a positive-polarity end portion of a smoothing capacitor, and a node between the primary winding and a primary side series resonance capacitor. Thus, a resonance pulse voltage generated in the choke coil winding is superimposed on an AC voltage in the primary winding. Also, a primary series resonance current is caused to separately flow through the choke coil winding.

摘要： A full wave DC/DC converter magnetically integrates into the transformer assembly the functions of the resonant inductor, magnetizing inductor and the output filter inductor. The primary and the secondary windings are assembled on a gapped center leg of an E-core, while two output filter windings with an equal number of turns are assembled on gapped left and gapped opposed side legs of the E-core. The length of the gaps in the side legs is selected so that the DC current does not saturate the side legs. The two filter windings are connected in series and are oppositely polarized so that the voltages induced in these windings by the primary winding flux cancel each other.

摘要： An energy transfer element having an energy transfer element input winding and an energy transfer element output winding. In one aspect, the energy transfer element input winding is capacitively coupled to the energy transfer element output winding. The energy transfer element is capacitively coupled to electrical earth. One or more additional windings are introduced as part of the energy transfer element. The one or more additional windings substantially reduce capacitive displacement current between the energy transfer element input winding and energy transfer element output winding by balancing the relative electrostatic fields generated between these windings and/or between the energy transfer element and electrical earth by canceling the electrostatic fields generated by all windings within the energy transfer element relative to electrical earth through the selection of the physical position and number of turns in the additional windings.

摘要： A power supply for supplying power to a load comprises a coupled inductor having a primary winding, at least one secondary winding, and a regulation circuit coupled to the primary winding that allows current or voltage to be supplied to the coupled inductor for a time duration, An error detection circuit is coupled to the secondary winding to compare a voltage or current supplied to the load against at least one threshold. Upon exceeding the threshold, the error detection circuit alters the voltage or current at the secondary winding, which causes a reflected feedback signal to be generated. A reflected feedback regulation circuit coupled to the primary winding provides an information signal to the regulation circuit responsive to the reflected feedback signal. The information signal increases or decreases the time duration to regulate the power supplied to the load.

摘要： Disclosure is made of an integrated-magnetic apparatus, comprising: winding structure for insulatingly carrying at least two generally flat, laterally offset and spaced apart electrical windings of a power converter around an aperture; a core having a flat exterior face, an interior cavity and an un-gapped core-column that is located within the cavity and that passes through the aperture of the winding structure; flat-sided surface carried by the core and forming an interior chamber that is located adjacent to the flat face of the core and forming a core-column that has a gap and that is located within the chamber; and structure, located around the gapped core-column, for carrying a third electrical winding of the power converter. The first two electrical windings are substantially located within the cavity and are adapted to be transformingly coupled together through the core. The third electrical winding is adapted to be inductively coupled through the gapped core-column to the other electrical windings, and is phased to have the magnetic flux passing through the gapped core-column substantially in the same direction as the magnetic flux passing through the un-gapped core-column and to have substantially the same AC components of flux in the gapped core-column and in the un-gapped core-column.
