摘要： A power supply device and a single photo-coupler control circuit thereof are provided. The power supply device includes a single photo-coupler control circuit, a main converter and an auxiliary converter. The main converter connects to an output load. The auxiliary converter connects in parallel with the main converter. The single photo-coupler control circuit, also connected to the output load, monitors the status of the power supply device and controls the main converter and the auxiliary converter accordingly. The single photo-coupler control circuit only has one photo-coupler. The main converter and the auxiliary converter together provide a first output to the output load when the power supply device works in a normal mode. The main converter is turned off so that only the auxiliary converter provides a second output to the output load when the power supply device works in a standby mode.

摘要： A power supply device and an operating method thereof are provided. The power supply device includes a main converter and an auxiliary converter. The main converter includes a power factor corrector (PFC), a first capacitor that connects in parallel with the PFC and a DC/DC converter that connects in parallel with the first capacitor. The auxiliary converter is connected in parallel to the main converter. When the power supply device operates in a normal mode, the main converter and the auxiliary converter together provide a first output to an output load. When the power supply device is in a standby mode, the DC/DC converter is turned off so that only the auxiliary converter provides a second output to the output load. Meanwhile, the PFC is in operation to maintain the voltage of the first capacitor in order to meet the demand of the output dynamic response of the main converter.

The main circuit has at least one output port for converting an input voltage into an output voltage at the output port. The first control circuit is used for controlling the main circuit under the normal operation mode. The second control circuit is used for controlling the main circuit under the standby operation mode. And, the switching controller processes a control signal to control the first control circuit and the second control circuit under either of the normal operation mode and the standby operation mode in response to a load status of the output port.
