Reliable electrical power is a milestone for modern society and economy. Multilevel power converters represent a potential breakthrough in employing switching converters for flexible ac transmission system and custom power application. This paper presents the design and realization of the prototype of a 1.5 kW mono phase 5-level cascaded inverter with PWM modulation. The prototype has been tested and the output waveforms have been investigated. The results confirm the goodness of these devices in synthesizing a desired ac voltage from several level of dc voltage with a good control of the frequency, the voltage output (including phase angle) and the active reactive power flow
