Latest Patents
One of Ziang Chen's latest patents is a "Wireless Power Transfer System." This system features a class DE inverter designed for efficient power transfer to a load. It includes a half-bridge circuit, a zero voltage switching (ZVS) tank, a shunt capacitor array, an evaluation circuit, and a controller. The half-bridge circuit consists of two transistors connected in series, each driven by a gate driving signal with a specific duty cycle. The ZVS tank, which includes two capacitors and an inductor, is electrically connected to the half-bridge circuit. The shunt capacitor array has tunable capacitance, allowing for optimization. The evaluation circuit calculates the power conversion efficiency, while the controller adjusts the duty cycle and capacitance to maximize efficiency.
Another notable patent is the "Method and Apparatus of Dead Time Tuning in an Inverter." This method prevents shoot-through currents and reduces body-diode conduction time in an inverter circuit by adjusting the dead times for transistors. A sensing resistor monitors the temperatures of the transistors, and a delay generator modifies the delay times based on this data. A dead time generation unit then adjusts the dead times for the transistors accordingly.
