Latest Patents

Andrew Chan holds a patent for a Bi-lateral four quadrant power converter. This advanced power converter is designed to supply alternating current (AC) or positive and negative direct current (DC) output voltage while isolating the output voltage from the input power source. The converter features a pulse width modulator that converts power amplitude signals into pulses of proportionate width. Additionally, a power driver circuit applies these pulses to a synchronous demodulator and low pass filter via a pulse transformer. The design ensures a low output impedance is presented to all output disturbances, allowing the converter to source or sink current in true four quadrant operation. This includes the capability of passing power from output to input when a load voltage exceeds the intended supply voltage.
