Introduction

Randhir S Malik is a notable inventor based in Succasunna, NJ (US). He has made significant contributions to the field of power conversion technology, holding two patents that showcase his innovative approach to electrical engineering.

Latest Patents

One of his latest patents is a self-oscillating high frequency power converter. This invention utilizes a MOSFET power transistor switch with its output electrode coupled to a tuned network that operatively limits the voltage waveform across the power switch to periodic unipolar pulses. The transistor switch operates at a high radio frequency, allowing its drain to gate interelectrode capacitance to serve as the sole oscillatory sustaining feedback path of the converter. Additionally, a reactive network, which is inductive at the operating frequency, couples the gate to source electrodes of the transistor switch. This network includes a variable capacitance that adjusts the overall reactance, thereby regulating the converter's switching frequency to provide voltage regulation. Another significant patent is a current limit shutdown circuit with time delay. This off-line switcher flyback-type power converter circuit is designed with energy and operative control circuits that operate off a tertiary winding of the power transformer. The delayed current shutdown circuit allows for starting under high demand current loads, supplying the load with bursts of current as startup is cyclic, and delayed shutdown is also cyclic in this situation.
