  Electric Vehicle (EV) chargers are the need of the hour as EVs have invaded
the commercial automobile market. The Three-Phase Three-Switch (TPTS) converter
has features which make it ideal to act as the charging station because of its
high efficiency at peak power rating. Traditionally, control of the TPTS
converter has been achieved by the Space Vector (SV) based modulation scheme
whose implementation is burdensome due to the trigonometric calculations
involved. This paper introduces two simplified carrier based modulation
schemes, which greatly reduce the implementation difficulty, as they require
minimum mathematical computations. A quantitative comparison is made between SV
scheme available in literature with the simplified scheme proposed here. The
methodology followed to obtain the carrier waves is also provided. All the
modulation schemes are validated with the help of a 1 kW hardware prototype.
