Electrical power switching module is used on hybrid electric vehicles to achieve high reliability

摘要

The electrical power switching module [100] consists of an array of 3 x 3 electro mechanical relays [110] each of which has a fixed contact [112], a movable contact [114] and a coil [116]. In order to obtain a reliable switching under high, inductive loads each stage includes a magnet [118] that reduces contact arcing effects.
