His work focuses on enhancing the efficiency and performance of power converters, which are essential components in various electronic devices.

Latest Patents

One of his latest patents is a low-cost high-efficiency power converter. This switch mode power converter achieves high efficiency through zero voltage switching (ZVS) by utilizing an auxiliary switch, a capacitor, an auxiliary winding, and an inductor. The technique can be applied to various types of converters, including boost, buck-boost, buck, isolated forward, or isolated flyback converters. The auxiliary switch is activated before the main power switch, allowing the capacitor to energize the inductor and facilitate current flow into the auxiliary winding. This innovative approach significantly reduces the switching loss of the main power switch.

Another notable patent is a low-cost AC-to-DC converter that features reduced harmonics in the input current. This converter draws input current through an inductor and operates efficiently when the input voltage is sufficiently high. When the switch is on, current flows through the inductor to the transformer and then to the storage capacitor. This design minimizes the number of circuit components while effectively managing input current harmonics.
