Description

technical field [0001] The invention relates to the field of power supply, in particular to a power supply circuit suitable for an intermediate frequency electrotherapy apparatus. Background technique [0002] The intermediate frequency electrotherapy device is an intermediate frequency current modulated by low frequency. This not only retains the characteristics of low-frequency electricity, but also brings into play the characteristics of medium-frequency electricity. Electrotherapy has therapeutic effects such as analgesia, swelling, inflammation, desensitization, muscle spasm relief, tissue tension enhancement, and recovery of normal nerve conduction and regulation functions. . The intermediate frequency electrotherapy instrument contains a lot of electronic components, and there are many electronic components in it, and the operation of each electronic component needs to provide power, such as operational amplifiers, controllers, etc. Since the power supply voltage of...
