ABSTRACT:
An inverter for producing a one or three phase output with neutral is disclosed. An LC resonant circuit is selectively switched by an inverter to produce one or three phases having a fundamental frequency equal to the frequency of each switching circuit within the phases of the inverter. The outputs are filtered to remove higher harmonics to pass the filtered output to the load. Energy is fed back into the resonant circuit by short circuiting the switching circuits at the time that the ouput voltage across a switching circuit is zero to minimize switching losses.
