Latest Patents
One of Yi-Hsin Leu's latest patents is titled "Power supply having multi-vector error amplifier for power factor correction." This invention features a regulated power supply that utilizes a multi-vector error amplifier. The amplifier generates an error signal that regulates the switching mechanism of the power supply. It is designed to provide a low distortion error signal during steady-state operation while responding quickly and smoothly to sudden load changes.
Another notable patent is the "PWM controller regulating output voltage and output current in primary side." This PWM controller offers a method to control the output voltage and current of the power supply without requiring a feedback control circuit on the secondary side of the transformer. To enhance regulation, the controller incorporates an adaptive load and a feedback synthesizer, which work in conjunction with the auxiliary winding of the transformer to maintain a constant output voltage. Additionally, a programmable power limiter is included to manage the power delivered from the primary side to the output, adjusting the power limit based on changes in output voltage.
