Optocouplers for Variable Speed Motor Control Electronics in Consumer Home Appliances
More InfoLess Info
Home appliances are a major area where three-phase PWM motor control drives are finding increasing applications. It is in the area of optically isolated gate drivers and optically isolated analog current and voltage sensors that modern, state of the art, low cost, and reliable optocouplers are becoming the component of first preference among designers. This paper examines optocouplers for variable speed motor control electronics in consumer home appliances.
