CKC & Partners Co., Ltd.
Isolated power control device, power conversion device and isolated power control method used in power conversion device
An isolated power control device that includes an auxiliary isolated power circuit and a voltage level identification unit is provided. The auxiliary isolated power circuit includes a transformer module, a control module, and a switch module. The transformer module includes a primary side and a secondary side. The control module generates a switch control signal according to a primary side remote on/off control signal. The switch module is conducted according to the switch control signal to transmit an input auxiliary power signal to the primary side of the transformer module such that the auxiliary isolated power circuit generates a target voltage signal having a plurality of voltage levels. The voltage level identification unit receives the target voltage signal to output a secondary side remote on-off control signal to control a main isolated power device.
