| description | PROBLEM TO BE SOLVED: To reduce a leakage noise by suppressing a spike voltage generated at an output voltage due to a deviation of generating voltage on/off timing of each single phase inverter in a gradation control type power converter which connects AC sides of a plurality of single-phase inverters (a Va inverter, a Vb inverter and a Vc inverter) in series and which outputs in combination of the selected each single-phase inverter. SOLUTION: A delay circuit 51 for regulating on/off timing of a drive signal of a switching element is provided at each single-phase inverter, and the spike voltage, generated when an output voltage gradation of a single phase multiplex converter having the single-phase inverters connected in series with each other is changed, is suppressed.
