The invention discloses an adapter with low standby loss, and an electronic system with low standby loss. The adapter comprises a rectification unit, a power factor correction unit, a standby circuit,a load plug connection detection circuit, a first power conversion circuit, a second power conversion circuit, and an auxiliary voltage control circuit. When a load device is connected to the adapter, a first grounding end of the first power conversion circuit and a second grounding end of the second power conversion circuit are in a short circuit state, thereby enabling the load plug connectiondetection circuit to be connected and transmit a first signal. After the auxiliary voltage control circuit receives the first signal, the auxiliary voltage control circuit is connected so as to drivethe first and second power conversion circuits to start to convert a first voltage into a first output voltage and a second output voltage.
Description
technical field [0001] The invention relates to an adapter and an electronic system, in particular to an adapter with low standby loss and an electronic system with low standby loss. Background technique [0002] An adapter is a common electronic device; usually, the adapter is used to receive and convert AC power into DC power, and output DC power to the back-end load device to drive the load device, so the adapter is very important in the electronic field . [0003] Generally speaking, when the adapter is not connected to a load device, the adapter stops converting and outputting power and enters a standby mode. In the standby mode, in order for the adapter to quickly enter into a working state, the internal circuit of the adapter still has a standby loss, which will cause a waste of energy. In addition, when the adapter is reconnected to the load device, the adapter must be able to automatically reset and start (auto re-start) quickly and accurately to supply power to t...
