摘要

Direct current motors are used for blower fans as well as for many other systems in vehicles. In this study, it was suggested to use an asynchronous motor instead of the direct current motor for the blower fan. Therefore, an induction motor driver was designed. The purpose of designing this driver was to allow the use of asynchronous motors instead of the brushed direct current motors utilized in automotive ventilation systems. Power and control circuits were designed. A three-phase variable frequency voltage was obtained using an inverter circuit designed with metal-oxide-semiconductor field-effect transistor semiconductor elements from the direct voltage. The voltage/frequency control method was applied to the induction motor. The power circuit was designed using three npn-type and three pnp-type metal-oxide-semiconductor field-effect transistors, in order to reduce the number of independent sources. The direct current motors generally used in automotive ventilation systems have 12 V operating voltage, so the driver was designed to be used in the 12-18 V range. In this study, the alternating current driver was used for a 90 W asynchronous motor and drive at 12 V and 18 V variable input voltage values. The dsPIC33fj32mc204 microcontroller was used to achieve variable frequency and speed control.
