Matrix (MC) and indirect matrix (IMC) converters are direct three-phase to three-phase power converters providing variable frequency and amplitude control of their output voltage. These converters are compact solutions which can be used on industrial adjustable speed drive applications for induction motors. This paper deals with the comparison of the matrix and indirect matrix converter silicon losses...
This article presents speed controlling for single phase induction motor. Principally, 9-level, diode-clamp inverter used to control voltages per frequency is widely used because of its high efficiency to control the motor. In this article, ARM7 model ADU7024 is used as microcontroller to generate eight pulse signals and send to the output voltage amplifier by co-connecting to the modulation module...
This paper deals with energy optimal control of induction motor dives. When motor operate at given steady-state operation point, the optimum control efficiency is acquired by seeking the different voltage-frequency ratio so that the active power absorbed by the motor is minimization, that is improve operational efficiency and achieve the purpose of energy saving. But the minimum active power also...
