Abstract: PROBLEM TO BE SOLVED: To provide a DC-DC power converter which supplies control power to a load. SOLUTION: FETs Q1, Q2 have parasitic capacitances between gates and sources, parasitic capacitances between the gates and drains, output capacitances, and intrinsic diodes. A transformer T1 has a primary winding 38 connected between a connecting point 24 of the FETs and a connecting point 34 of power sources 30, 32, a secondary winding 40 and an inductance 42 which is in series with the primary winding. A drive transformer 80 has secondary windings 84, 86 connected with FET drive circuits 60, 62, and a primary winding 82 which is connected with a control circuit 90, for making the drive circuits operate and not operate alternately. The drive circuits 60, 62 start the charging of the parasitic capacitances between the gates and the drains of the related FETs.  When voltage between the gates and the drains reach the threshold, effective output capacitances of the FETs are discharged by having the inductance of the transformer T1 discharged by a current flowing in the primary winding. After that, the FETs are so operated that the intrinsic diodes start energizing.
