Our single-phase AC induction motor reference design using the MC68HC908QT4 MCU is intended to substitute commonly used triac phase angle control drives.
- Capable of supplying a single-phase AC. induction motor (or general AC inductive/resistive load) with varying voltage.
- Uses pulse width modulation technique (PWM) and, compared with phase angle control used for triacs, produces much lower high harmonic pollution and complies with EMC/EMI regulations.
- Suitable mainly for low-cost designs and intended for use in consumer and industrial products such as washing machine, dishwashers, ventilators, compressors and everywhere that system cost is considered.
