I am designing charge controller for 12V battery through solar panel.Initially I am using DC source instead of PV panel in PSIM 9.3 32 bit trial version.Charge controller is basically step up capacitor based boost converter which is voltage doubler.Simulation of voltage doubler has been done in PSIM correctly..but problem is now to maintain fixed 14V at converter output irrespective of input as this converter has to charge battery at constant 14V.One control technique is through variable duty cycle of switches through PWM;in which output of converter will be compared to fixed 14V reference voltage and comparator generates error signal which will then be compared to sawtooth signal which provides pulse width or PSIM but result not correct..whatever I applied on input same thing appear on output..no voltage regulation occuring.
Please correct errors in this circuit if any and guide.I am attaching jpg file of both converter one without voltage regulation and other with voltage regulation but it's result not correct.
