Abstract
A DC to AC converter for solar energy installations is configured to convert DC input power at a first voltage from a floating DC source to a desired AC output power waveform. The converter is configured to cause an AC output waveform at a first repetition frequency and having a voltage relative to one of at least one ground, neutral, or reference potential terminals to appear with a unique phase at each of a number N at least equal to one of a set of live AC output terminals; and a common-mode voltage waveform at a second repetition frequency to appear relative to one of the ground, neutral, or reference potential terminals and in the same phase on both of positive and negative DC input terminals, varying alike in voltage while maintaining a substantially constant differential voltage between them, the variation in voltage having substantially the same common waveform on both the positive and negative DC input terminals and transitioning between a greatest negative and a greatest positive value at a frequency equal to N times the output AC waveform first repetition frequency.
