<p>PURPOSE: A DC power supply is provided to constantly maintain a load current by adjusting the turn-on time of a semiconductor device comprising a converter according to a DC input voltage. CONSTITUTION: A first voltage sensor(101) detects a DC input voltage(Vs). A converter(102) converts DC power of a DC voltage source(100) into AC power. A current sensor(104) detects a secondary current(I2) of a transformer(103). A rectifier circuit(105) converts the AC power from the transformer into DC power. A resonance circuit is composed of a resonance switch(106) and resonance condenser(107) connected to a DC output side of the rectifier circuit in parallel.</p> |
