Abstract
A resonant-type five-level pulse-width-modulated (PWM) inverter for small-scale photovoltaic systems is presented. The output waveform of this inverter has multiple levels of voltage, achieved by connecting two units of power source in series or parallel. The operation of and experimental results for this inverter are presented. An efficient circuit which uses two inductors with coupling is proposed to attain high efficiency with this inverter. The inverter also exhibits reduced low-order harmonics
