<p><P>PROBLEM TO BE SOLVED: To provide a DC voltage converter which is equipped with soft switching and has a single transformer and can generate two or more output voltages. <P>SOLUTION: This invention relates to a DC voltage converter equipped with soft switching, where the primary side is a type of half bridge constitution and the secondary side is a type of pseudo resonation half waves. The above converter further has resonance circuits (Lf, Cr1, D1 ; Lf, Cr, D1) which generate half wave resonance currents in secondary winding (Ls), charge a first load capacitor (Cs1), and generate first DC voltage (Vs1). The above converter further has inductive circuits (D2, Lr, and T3) which are connected between the above secondary winding and a second load capacitor (Cs2) and generate currents, charge the second load capacitor while a part of the half waves of the resonance currents flows to the secondary winding, and generate second DC voltage (Vs2). <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
