PULSE WIDTH MODULATION METHOD FOR POWER CONVERTER EQUIPMENT

PROBLEM TO BE SOLVED: To reduce substantial switching loss by performing pulse width modulation by comparing a voltage and a frequency supplied to a load to predetermined values and by stopping the switching of a phase having the largest value of a phase current in a small section. SOLUTION: By cons...
