Latest Patents

Huang's latest patents include an "Active Current Sharing Circuit" and a "Soft-Start with Back Bias Conditions for PWM Buck Converter with Synchronous Rectifier." The Active Current Sharing Circuit provides a plurality of paralleled DC-DC converters, each equipped with a lossless inductor-based current sensing circuit. This design allows for sensing the average current of the associated DC-DC converter through its output inductor. The circuit enhances current sharing levels at a lower cost while reducing wiring complexity and the number of components. In an alternate embodiment, the inductor-based current sensing is replaced with a resistor-based current sensing, achieving comparable current sharing levels albeit with higher loss.

The Soft-Start with Back Bias Conditions for PWM Buck Converter with Synchronous Rectifier efficiently prevents the synchronous rectifier from turning on during predetermined conditions. This design prevents current from reversing through the synchronous rectifier during critical soft-start conditions. The circuit controls the synchronous rectifier during the soft-start time for a non-isolated DC-DC buck converter, thereby addressing the back bias condition during the soft start process.
