• Ac-ac matrix converter
• Soft switching
• Zero current switching (ZCS)
• Zero voltage switching (ZVS)

This paper is focused on a new modification of a single phase ac-ac matrix converter with auxiliary resonant circuits for the ac locomotive applications. Soft switching ac-ac matrix converter with additional auxiliary resonant circuits has been proposed. The major advantage of this topology is to reduce the switching losses to enhance the operation of hard switched ac-ac matrix converter. The main aim of this paper is to achieve the zero-current turn-off of the main switches. This paper describes the operation, simulation analysis and its experimental validation for the proposed 76 V/136 W converter.
