Passive triac output asymmetry detector

摘要: A passive circuit for protecting an AC driven load controlled by a solid state device such as triac or the like. The is coupled to and controller element effects shutdown of power control whenever asymmetrical input measured over predetermined number cycles received from element. includes inductor having thermal link thereto, being connected in parallel which other similar device. Should be controller, could occasioned failure itself, across will become heated power, causing heating link. At temperature, open, removes both
