Converting DC to AC: Basic Principles of Inverters

Traditionally DC power conversion was achieved through a motor generator set, where a motor operating on DC power directly turned a generator to produce the required AC power. The opposite of this, an AC motor driving a DC generator was called a converter, hence the name inverter when applied to a DC to AC gen-set, the name stuck.
