Latest Patents

Chun-Shih Huang's latest patents include a flyback power converter, a secondary side control circuit, and a control method thereof. This invention provides a flyback power converter that converts an input voltage to an output voltage while supplying load current to a load circuit. The flyback power converter comprises a transformer circuit, a power switch circuit, a switch current sense circuit, a primary side control circuit, and a secondary side control circuit. The secondary side control circuit adaptively adjusts the frequency of a zero of a compensator gain function and/or a mid-frequency gain of the compensator gain function based on the load current. This ensures that the number of poles of the system open loop gain function is at most one more than the number of zeroes of the system open loop gain function under a crossover frequency.

Another significant patent is the voltage converter controller and voltage converter circuit. This invention includes a voltage-drop compensating circuit designed to compensate for voltage drops between the output voltage and a load. The voltage-drop compensating circuit features a trans-conductance stage and a squarer. The trans-conductance stage outputs a compensating sink current to a voltage dividing terminal of the output voltage and a compensating source current to a reference voltage terminal of an error amplifier. The squarer is coupled to the output terminal of the error amplifier, enhancing the overall performance of the voltage converter.
