Power supply for electronic circuit of electrical household appliance e.g. washing machine, has transformer provided with insulated winding enclosing non-insulated winding, where insulated winding is associated with clipper

摘要

The supply has a rectifier unit with a non-insulated output providing a non-insulated dc voltage. A control loop connects the rectifier unit with a clipper in return path. A transformer is provided with an insulated winding (7) enclosing a non-insulated winding (12). The insulated winding is connected to a rectifier unit and is associated with the clipper.
