Hi, me again,
where I am inverting 160VDC to 110VAC by way of an H bridge with modified sine wave. It will basically be mains power but the main purpose will be to charge laptops and similar devices. I have been given the design restraint of 3A output max and I have developed a way latching the circuit to shut down when it goes above 3A. But after posting here yesterday I was wondering if regulating the current would be a better solution. The best way I have seen this done is by reducing the voltage.
So my main question is would this method of current regulation work for my situation? from what I have seen laptop chargers are generally rated to accept a minimum VAC of 100 so that would give me about 10Vrms to play with. Would I be able to reducing the voltage more? Is there a better DC current regulating methods? (one that doesnt involve switching)
thank!
