I have a 300W 12V to 230V power inverter which has what is described as
a 'modified sine' wave output. Is this synonymous with 'square wave'?
If it is really square wave what can I do do protect switch mode power
supplies as loads. Will a large pi-network filter help? Any ideas
what 'modified sine' actually means and what I can do to improve it.
