Abstract: This paper presents the single phase matrix converter topology that will operate as an uninterruptible power supply circuit. A single circuit is developed that performs both the rectifier and inverter operation which also incorporate active power filter. Commutation strategies are also implemented with reduction in spikes, a common phenomenon in matrix converter topologies. Experimental setup and results are presented to verify that the proposed technique is feasible. This single phase matrix converter topology will be operating as an inverter and controlled rectifier in which H-bridge inverter transforms a DC input into an AC output. The pulses for single phase matrix converter are generated by using pulse width modulation technique. The various building blocks to the development of a new uninterruptible power supply circuit are developed centred on the use of a single phase matrix converter.

Keywords: Pulse width modulation, matrix converter controlled rectifier, UPS, MOSFET – Metal oxide semiconductor field emitting transistors
