I have a personal question about the ruggedness of consumer entertainment equipment to powerline distortion, and I would like to hear any thoughts you might have about this.
The potential victims are 120 VAC powered televisions, radios, disk players, computers, etc. The environment is a recreational vehicle which uses an inverter to create 120 VAC from onboard batteries. In current practice, inverters fall into two categories; very expensive "pure" sine wave and less expensive "modified" sine wave output. I can understand "pure" as being relatively clean, but "modified" is a very subjective term which the inverter manufacturers don't seem willing to define. First, is there some definition of just how much distortion is allowed for the category of "modified" sine wave? And second, has anyone done any examination of typical consumer electronic equipment to determine susceptibility to "modified" sine wave power? Could we say that compliance with typical EN CS requirements would be good enough to ensure operation in the "modified" sine wave power environment? Thanks in advance!
