Title: Wing K Eng: Innovator in Power Conversion Technology
Introduction
Wing K Eng is a notable inventor based in Stanhope, NJ (US), recognized for his contributions to power conversion technology. With a total of 4 patents, Eng has made significant advancements in the field, particularly in reducing harmonics and improving power efficiency.
Latest Patents
Eng's latest patents include a "Single stage power factor corrected converter having isolated output." This innovative power converter operates to reduce harmonics at an AC input by controlling its power switching, ensuring that the current waveform in a switched inductor closely resembles a rectified version of the input AC voltage waveform. Additionally, the voltage spikes induced by the switching of the inductor into circuitry that includes the leakage inductance of a power transformer are subdued by circuitry that temporarily absorbs the initial voltage spike and then delivers that energy to the output load of the converter. Another significant patent is the "Off-line switcher with battery reserve." This off-line switcher features an auxiliary winding on the secondary side of the power transformer, coupled by a power switch to a secondary voltage source, providing uninterruptible power to the output from either a primary AC or a secondary DC source. The power switches that couple both primary and secondary source voltages to the power transformers are driven at identical duty cycles by a common regulation control, allowing for efficient power management.
