Latest Patents
Mingliang Chen holds a patent for a bi-directional magnetic isolator. This device is designed to pass an isolated housekeeping supply voltage from an input side to an output side while also transferring an isolated error signal from the output side back to the input side. The dual functions of this magnetic isolator ensure that a power supply operates effectively during both no-load and output short circuit conditions. The isolator consists of a pair of pulse transformers, each with primary and secondary windings. The housekeeping supply voltage is transmitted through one of the pulse transformers by pulsing the supply voltage from the primary winding to the secondary winding, followed by rectification and storage of the rectified voltage on an output capacitor. The error signal is transferred in the opposite direction through the second pulse transformer using a similar technique, where the error signal is chopped to create a pulsating signal that is then rectified and stored as a voltage representative of the error signal. A fixed on-time clock is utilized to pulse both the supply voltage and the error signal.
