Microcontroller Controlled IGBT Z-Source Matrix Converter

In this paper, the authors present a single phase z-source buck-boost matrix converter which can buck and boost the output voltage with step change frequency i.e. both the voltage and the frequency can be steeped up or steeped down. Also, this converter uses a safe-commutation technique to conduct current in a continuous path, resulting in the elimination of voltage spikes on switches without the need for a snubber circuit. It has no energy storage devices, performing the energy conversion by directly connecting input with output phases through bidirectional switches.
