Description

technical field [0001] The invention relates to a power supply circuit, in particular to an efficient and environment-friendly AC-DC conversion isolation power supply circuit. Background technique [0002] AC power supply, that is, AC power supply, is generally 220V input AC power, and 220V input AC power is introduced in the homes of ordinary residents, but at present, many electrical appliances need to use DC power, and also require a large current, so the development of a The power supply circuit of AC-DC conversion is very common. Of course, at present, the transformer part of the AC-DC conversion circuit needs to use electromagnetic coils for voltage transformation, but if electromagnetic coils are used for voltage transformation, there will be the following problems: Higher production cost is required for high voltage, and it needs to occupy a large space; secondly, there will be certain electromagnetic pollution when using electromagnetic coil for voltage transformati...
