Summary:The trend in electrical drives is to integrate the frequency
converter, the electrical motor, and even the gear or the pump into a
single unit, in order to reduce the costs, to increase the overall
efficiency and the equipment reliability. This paper presents the first
integrated regenerative frequency converter motor for industry
applications, based on a matrix converter topology. The low volume, the
sinusoidal input current, the bidirectional power flow, and the lack of
the bulky and limited-lifetime electrolytic capacitors recommend this
topology for this application. This paper shows how the matrix converter
disadvantages-the lack of bidirectional power devices, the lower voltage
transfer ratio, and the overvoltages caused by the input filter during
power-up-that have delayed the industrial implementation have been
overcome. In order to demonstrate the validity of the solution, a 4-kW
matrix converter motor prototype is built using a standard frequency
converter motor enclosure for testing the requirements for an industrial
drive. The tests demonstrate the good performance of the drive
