I'm designing a circuit for battery charging, which will make use of boost converter topology. I have determined the input/output voltage and current parameters for the circuit. If I put a resistor at the output with value of V_out/I_out, the simulation works just fine. My question is; how can I set the current, so that if I put a battery at the output when the circuit is built, the current would be same as the pre-defined output current value. Also, does the output current depend on the characteristic of the source? Like if the power value of source is constant but input current and voltage changable with PWM at the switch (like a pv panel), what would the output current depend on? Many thanks.
"does the output current depend on the characteristic of the source?"
If the current required by the load does not exceed the max current of the source, the answer is NO.
The voltage source in this case will work as an almost ideal source and the current will depend solely on the output request.
