Please tell me a reliable and thought-out diagram of the power supply up to 3kW/310B, preferably transformerless. Input normal AC 220V 50Hz. As the planned load inverter and induction furnace.
Understand that a serious problem. =) In the Internet a lot of schemes are different, choose the really can not.
— Galvanic isolation optocouplers.
— At the input high frequency filter to prevent ingress noise into the network.
— Stabilization of the output voltage.
— Corrector of power factor
— Microprocessor control
— Adjustment of output voltage from 0 to 310B.
— Control electronics on a separate power source
In General, really need something like this in functionality, only with the specified output characteristics: www.soel.ru/cms/f/?/380058.pdf
Thanks in advance for any help!
PS: Pushed to electronics for beginners, because other electronics not stupid found. =)
