Abstract
A series multiplex inverter includes a power conversion unit, a drive signal generation unit, and a drive signal output unit. The drive signal generation unit generates n drive signals that cause different single-phase inverters of n single-phase inverters to output n rectangular wave voltages sequentially out of phase, where n is an integer of three or more. The drive signal output unit outputs the n drive signals to the n single-phase inverters in rotation that shifts, by p every m-fold time of half an output voltage period of the power conversion unit, the single-phase inverters corresponding one-to-one to the n drive signals in a combination of the n drive signals with different single-phase inverters of the n single-phase inverters, where m is a natural number and p is a natural number relatively prime to n or one.
