Compensation circuit for constant output voltage
A compensation circuit for constant output voltage is disclosed. The compensation circuit comprises a current source, a first switch, a controllable current source, a second switch, a logic NOT gate, a CV loop control module, and an input voltage detection module. The compensation circuit ensures a normal start-up, and substantially no additional power dissipation of the converter is generated at no load. Furthermore, the compensation circuit adjusts a compensation current according to at least one of a detected input voltage of the power supply converter and a working mode of the transformer, to obtain better precision of constant output voltage. The compensation circuit can be applied to occasions where extremely small standby input power dissipation or extremely high precision of constant output voltage is required.
