Abstract: PURPOSE:To make a boosting transformer small-sized by a method wherein a capacitor is connected in parallel with a rectification circuit between secondary output terminals of the boosting transformer and the rectification circuit and the series resonance frequency of a capacity obtained after the leakage inductance of the boosting transformer and the capacity of the capacitor have been squared by the turn ratio of the boosting transformer is set at 1.7 to 2.3 times the upper-limit value of an output frequency of a low-voltage AC power supply. CONSTITUTION:Regarding the frequency characteristic of a primary impedance of a boosting transformer 32 with reference to the output frequency of an inverter circuit 31 on the primary side of the boosting transformer 32, a frequency whose impedance displays a minimum value appears; the frequency coincides with a series resonance frequency of the leakage inductance of the boosting transformer 32 and a capacity obtained by multiplying the capacity of a capacitor 33 on the secondary side by the squared turn ratio of the transformer. Regarding the characteristic of a maximum output current, a large output current can be obtained when the ratio of the output frequency of the inverter circuit 31 to the series resonance frequency is between 1/1.7 to 1/2.3. As a result, the turn ratio of windings of the boosting transformer can be reduced to about 1/2 of the ratio of a primary voltage to a secondary voltage.
