Microcontroller-Based Variable Speed Drive for Three-Phase Induction Motor in Cooling Applications
摘要
This paper presents an electronic VSD (variable speed drive) for three-phase IM (induction motor) using a microcontroller. The VSD is designed for cooling applications where the 1M is coupled to a cooling fan. The drive receives temperature feedback from objects to be cooled and output a corresponding frequency to the IM. A prototype of the VSD is constructed to control a 175 W, four pole, squirrel cage three-phase IM. The heart of the control circuit is a low-cost microchip's PICI6F777 microcontroller which is programmed using C language to generate variable frequency SPWM (sinusoidal pulse width modulation) switching signals. These switching signals are fed to an 1GBT inverter. The VSD constructed can be switched between two modes of speed control" automatic temperature-controlled mode and manual user-controlled mode. Cost savings using the prototype are demonstrated.
