How does this circuit work ?
As it is a PIC based circuit I am asking the question in Micocontroller section.
Please see the attached circuits.
The Transformer is a Iron-Core Transformer. The FB Winding is used for Feedback to AC to adjust the output voltage.
The PIC circuit has a ZCD circuit. Don't know how it works.
There is a Relay 30 Amps. Why is it used ?
The circuit is of a 220-V 50 Hz Inverter.
My client says that the same transformer is used for both output (220V) and for charging the battery.
7.5V is stepped to 220V. 15V from Feedback winding goes through bridge, filter and zener to ADC for monitoring the output voltage level.
He says that when there is mains then the high side mosfets will be off and the low side mosfets will works as boost converter for charging the battery. If it is right then what signals I have to apply to the low side mosfets for charging the battery ?
