Latest Patents

Ya-Jiang Zhu holds a patent for a short circuit protection circuit for a pulse width modulation (PWM) unit. This invention includes a PWM logic control circuit, an under voltage lookout (UVLO) circuit, and an internal clock circuit. The UVLO circuit detects bias power (Vcc) and delivers a UVLO signal when the bias power is deemed excessively low. The PWM unit further comprises a short circuit detector, a short circuit recovery circuit, and a frequency multiplexer. The short circuit detector generates a short signal upon detecting the UVLO signal. The short circuit recovery circuit sets a predetermined recovery time and generates a recovery signal when this time elapses. The frequency multiplexer is triggered by the short signal during a short circuit event to change the switching frequency to a short PWM frequency, and it is triggered by the recovery signal to restore the original switching frequency. This patent showcases Ya-Jiang Zhu's expertise in enhancing the reliability and efficiency of electronic circuits.
