Title:
RESONANCE DC VOLTAGE CONVERTER
Document Type and Number:
Japanese Patent JP3927046
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To constitute a resonance DC voltage converter provided with an output current limiting means that controls an output current value in such a way as not to exceed prescribed current values including a rated current without using an output current sensor.
SOLUTION: The resonance DC voltage converter is provided with a transistor Q1 that turns on and off an input voltage, a resonance circuit 2 that generates a resonance current at a prescribed cycle, and a control unit 3 that outputs a switching signal 33 at the switching cycle set to turn on and off the transistor Q1. A computing part 30 is incorporated that calculates the switching cycle that corresponds to the prescribed current values to output the switching signal 33 at the calculated cycle or more.
