Embodiment Construction
[0030] The present invention will be described in further detail below with reference to the accompanying drawings and examples. However, the invention is not limited to the examples given.
[0031] An embodiment of the present invention aims to provide a high isolation and withstand voltage power supply, which requires high output power, precision and efficiency while ensuring high isolation strength and small volume.
[0032] In order to achieve this goal, this embodiment first finds a new way on the power supply circuit, abandoning the feedback mode of TL431 plus optocoupler and magnetic feedback common in the prior art, and adopting the self-feedback mode of the primary side, that is, removing the feedback mode of the optocoupler Or the path from the secondary side to the primary side in the magnetic feedback mode (remove TL431 and optocoupler in the feedback mode of TL431 plus optocoupler; remove the feedback transformer in magnetic feedback), change the output from one g...
