摘要： A unique multi-output isolated buck DC-DC converter system is disclosed. The converter system has non-pulsating input and output current waveforms. The converter can be adapted to two- or three-bobbin integrated-magnetic embodiments, or in discrete-magnetic form. One embodiment of the converter comprises capacitor means joined at one end to a first common core inductor and joined at its opposite end to a second common core inductor; and switch means having a duty cycle, for alternately joining an output lead to one end of the capacitor means and to the opposite end of the capacitor means, such that a voltage proportional to "VD" is produced at the output lead when a DC voltage "V" is applied across opposite ends of the first and the second common core inductor.

摘要： A DC to DC converter is shown having an inductor with primary and secondary windings whose primary winding is serially connected to the center tap of the primary winding of a push-pull transformer. The primary of the transformer is then connected through its ends by a pair of transistor switches to ground while the ends of the secondary of the transformer connect through diodes to an output terminal. The ends of the secondary of the transformer also connect through diodes to the inductor secondary and then to the output terminal. The presence of the inductor prevents the voltage across the switches from becoming twice the input voltage as in conventional circuits. By equalizing the secondary to primary turns ratio between the inductor and transformer, it is possible to equalize the voltage output during the time intervals when the switches are on and off.

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.

摘要： An innovative start-up circuit is disclosed which uses ordinary solid-state components and which may be used with a wide variety of switched mode boost-buck integrated magnetic power converters, including those having only two winding bobbins, a boost section with enhanced gain, and several new and different core arrangements. The start-up circuit comprises a winding which is transformer coupled to the drive transformer, a capacitor which is charged by the application of power to the input of the converter, switching means for switching current from the input of the converter to the drive transformer in response to the charging of the capacitor, and means for preventing the capacitor from operating the switching means after the converter is placed into operation.
