Latest Patent Applications
Zen-Shan Chang has filed several patent applications that showcase his inventive capabilities. One of his latest applications is for a Converter-based Power Supply System for Reducing a Contract Capacity. This system includes a power supply controller, a first meter connected to the power supply controller, an alternating current load connected to the first meter, a second meter connected to the power supply controller, a grid connected to the second meter, converters connected to the alternating current load and the grid, and an energy storage unit connected to the power supply controller and the converters.
Another significant application is for an Asynchronous Sigma-Delta Modulation Controller. This constant-frequency asynchronous modulation apparatus includes a current feedback control unit connected to a constant-frequency asynchronous modulation unit. The current feedback control unit features a reference signal generator and an error amplifier. The reference signal generator provides an error, while the error amplifier generates an error-compensating signal based on this error. The constant-frequency asynchronous modulation unit is designed to adapt to changes in the reference signal, ensuring optimal performance.
