The invention discloses a power supply circuit based on light-coupled transmission and a light-coupled transmission module. Pulse signals of different pulse widths are adopted to represent different power supply voltages needed by a load, and corresponding identification signals are obtained through light-coupled transmission; an output voltage of a power supply module is adjusted according to the identification signals, and the resistance of a voltage division module can be changed in case of keeping an output voltage sampling signal to be invariable, so that the output voltage can be changed; besides, the value of the output voltage sampling signal can be changed in case of keeping the resistance of the voltage division module to be invariable, so as to change the output voltage. Since the pulse widths are adopted as transmission information, multiple situations can be more accurately recognized, and the requirement of transferring multiple signals can be satisfied.
Description
technical field [0001] The invention relates to the technical field of power electronics, in particular to a power supply circuit based on optocoupler transmission and an optocoupler transmission module. Background technique [0002] In many occasions, in order to meet the requirements of safety regulations, transformers or optocouplers are generally used to transmit signals. In the power supply circuit, it is necessary to identify the power supply voltage required by the power supply object, and transmit the electrical signal representing the required power supply voltage through the optocoupler to adjust the power supply circuit to output the corresponding power supply voltage to meet the needs of use. [0003] In the prior art, when an optocoupler is used to transmit signals, the optocoupler is generally operated in a linear state, and different signals are distinguished by different currents flowing through the primary side of the optocoupler to make the voltage drop of ...
