Abstract :
An AC light dimmer topology using two voltage-controlled symmetrical switches is presented. After an introduction of the silicon structure of these new engineering devices, their conduction losses are compared to today technologies. Gate driver circuits are presented to fulfill EN55015 standard with low commutation losses. The impact of the recovery current is also discussed
