Mr. Brain
Even i am not able to see the circuit. As you said if the input current is same as the output current then no need of any current limit only voltage is enough.
if your input current is more than battery charging current example if you have 20A,20V at the input side and your charging current is 1A,14.4V, you need to have a voltage limiter as well as current limiter. both voltage limit and current limit can be done using pwm. that pwm should be scaled...
ok am ready to help you but i need some specifications
what is your AC voltage input?
why you are going for zero cross detection?
what type of switch you are using to switch on the AC load? (TRAIC or Relay) what is there part number
what is your maximum AC load (power)?
provide me this details...
remember whenever you are using body diode mosfet, there will be a conduction from source to drain if source voltage is greater than drain voltage Vs>=Vd+Vth.
Vth = body diode drop
Vd = drain voltage
Vs = source voltage
if you are connecting drain to the power source, your power source will...
hi,
i have seen your circuit using lm339 it does not work because there is no negative voltage, if you connect your ground pin to negative voltage you will get the waveform. but in your circuit there is no negative voltage it is zero voltage ground. if you want to get an output waveform...
