PROBLEM TO BE SOLVED: To provide a power conversion device that can satisfy a requirement of reducing loss of power in a prior art.SOLUTION: A controller 7 switches at least one of a first switching element S5 and a fourth switching element S8 from OFF to ON at a first ON time point Ton1 in a first period in which the voltage of a secondary winding 21 (transformer voltage V1) is positive, switches at least one of a second switching element S6 and a third switching element S7 from OFF to ON at a second ON time point Ton2 in a second period which is subsequent to the first period and in which the voltage of the secondary winding 21 is negative, and controls the amplitude of at least one of an output voltage Vo and output current io by shifting at least one of the first ON time point Ton1 and the second ON time point Ton2.SELECTED DRAWING: Figure 5 |
