Title:
CONTROLLER OF AC ELECTRIC CAR
Document Type and Number:
Japanese Patent JPH06233538
Kind Code:
A
Abstract:
PURPOSE: To suppress the beat phenomenon of inverter current generated by an interference of pulse frequency with inverter frequency.
CONSTITUTION: A ripple voltage compensation converter 22 is provided so as to superpose the pulse voltage on the reverse phase DC voltage to compensate the pulse voltage of the DC output circuit of a converter 4, and the source voltage close to a perfect DC voltage is given to an inverter 5 to drive it, thereby suppressing the beat phenomenon of inverter current.
