Abstract
A power delivery system includes a PD source device and a PD sink device. The PD source device is configured to detect its connection status with the PD sink device and determine whether its power supply is high-voltage operation. When determining that the PD source device is supplying high-voltage power and detecting that the PD source device is detached from the PD sink device, the PD source device is configured to provide an oscillating rapid discharging path for its output capacitor, thereby rapidly reducing its output voltage and suppressing electrical arc.
