发明名称 Battery charger circuit with low standby power dissipation
摘要 The invention concerns an electronic circuit for reducing the current consumption of a transformer (1). This circuit comprises a control circuit in the secondary circuit of the transformer (1) and a switch (2), controlled by the control circuit, in the primary circuit of the transformer (1) for separating the primary circuit of the transformer (1) from the power supply (3). The control circuit comprises a detector (6) for detecting the no-load state of the transformer (1). If the transformer (1) is in the no-load state, the switch (2) on the primary side is opened at least temporarily.
