Latest Patents

One of Hung Ching Lee's latest patents is focused on power supplies with synchronous rectification. This invention includes a transformer, a rectifier switch, a secondary-side controller, and two diodes. The transformer consists of a primary winding, a secondary winding, and a detection winding, which are inductively coupled. The rectifier switch is connected in series with the secondary winding between two output power lines. The secondary-side controller is electrically coupled to the detection winding's ends, controlling the rectifier switch based on terminal signals. The two diodes are connected back-to-back in series between the two ends, with a joint connecting one of the diodes to an output power line.

Another significant patent involves dimming controllers and methods capable of receiving both PWM dimming signals and DC dimming signals. This dimming controller can adjust light-emitting devices based on the type of dimming signal received. A type identifier determines the signal type, generating a selection signal accordingly. A signal converter produces a first signal in response to the dimming signal, while a multiplexer forwards either the first signal or the dimming signal to a driver for the light-emitting device.
