Latest Patents

Tang is credited with 1 patent: “Highly Efficient Line Transient Protection Circuit for High Power Loads.” The invention uses a primary leg, a load circuit, and a secondary circuit to protect equipment designed to continue operating through a high line transient. Its load circuit can be configured for applications such as switching regulators, oscillators, push-pull circuits, boost converters, and buck converters.

A simple driver turns on a bypass n-channel MOSFET, helping reduce conduction losses under normal input-voltage conditions. The circuit also provides a programmable voltage clamp, set by selecting a zener diode. The design is intended to protect medium- to high-current circuits and may be useful in demanding applications, including military and medical equipment.
