Title:
BIDIRECTIONAL 4-QUADRANT POWER CONVERTER
Document Type and Number:
Japanese Patent JPS58151867
Kind Code:
A
Abstract:
A power converter which supplies AC or positive or negative DC output voltage with positive or negative current while isolating the output voltage from the input power source. This converter includes a pulse width modulator converts power amplitude signals to pulses of proportionate width. A power driver circuit applies these pulses to a sychronous demodulator and low pass filter via a pulse transformer. A low output impedance is presented to all output disturbances such that the converter can source or sink current in true four quadrant operation, including the passing of power from output to input when a load voltage exceeds the intended supply voltage.
