Latest Patents

Hu’s listed inventions address micro-inverter design and converter control.

“Power converter and control method therefor, uninterruptible power supply, and power supply system” describes a micro inverter with transformer windings, power conversion circuits, and an energy storage buffer circuit. During periods of double-frequency ripple power, the controller manages charging and discharging so energy can be buffered through the transformer and transferred between conversion circuits. The described approach aims to reduce inverter volume and cost while improving power-converter reliability.

“Converter and control method of sending PWM driver gating signal thereof” concerns pulse-width modulation control for a converter. When the output alternating-current voltage is in the specified O area, the converter switches between upper and lower half-bridge straight-through modes. This control is intended to maintain a freewheeling path for inductive-component current while avoiding a straight-through state in a secondary-side switching transistor.
