Abstract

PURPOSE: To decrease the number of voltage conversion stages and to improve the efficiency of conversion, by converting an AC voltage from a three phase AC power source directly into a high frequency AC voltage.
CONSTITUTION: A DC power supply is composed of an input filter 3 for a three- phase AC power source, a transformer 5, an output rectifier 6, an output filter 7 and others to supply a load 8 with power. In this case, said power supply is provided with a switching part 10 and a control circuit 11 to switch AC voltage from said three-phase AC power source 1 at a higher frequency by said switching part 10 via said input filter 3. Then, a high frequency AC voltage is generated on the output side of said transformer 5. Also, said control circuit 11 detects each line voltage from the three-phase AC power source 1, controls the ON pulse width of semiconductor switches 12∼17 between respective lines so that said pulse width is proportional to said line voltage, and determines which switch to be turned ON. Thus, the efficiency of conversion is improved, because said AC voltage can be directly converted into a high frequency AC voltage.
