摘要： Disclosed is a full-wave output type forward converter wherein a main transformer having a primary winding connected in series with a switching element includes two secondary windings as winding halves divided by a center tap and electromagnetically coupled. A leakage self inductance can be reduced to obtain a high-frequency, high-power arrangement.

摘要： A device including a main circuit comprising a switching main transistor unit, a smoothing reactor, a smoothing condenser and a commutation diode. To control the conduction and nonconduction of said main transistor unit by means of the output obtained by detecting and amplifying the output voltage of said main circuit, the main transistor unit comprises at least two main transistors connected in parallel with each other. A secondary winding of a current transformer is connected between the bases of the main transistors. A parallel circuit comprising a diode and a condenser is connected between the neutral point of the secondary winding and the emitters of the main transistors. A control circuit comprises two transistors which are conductive and nonconductive alternately and outputs derived from the latter transistors are applied alternately to two primary windings of the current transformer and provision is made to short the ends of the primary winding of the current transformer while the two transistors of the control circuit are both nonconductive.
