Series-mode filters contain residual surge voltage within normal power line voltage ranges while avoiding the inconvenience and costs of downtime
J. RUDY HARFORD, Zero Surge Inc.
WITHIN THE MODERN home and workplace, an ever-growing number of sensitive electronic systems are vulnerable to power line surges that can disrupt or damage vital equipment. Obviously, a filter that would prevent such problems is a very desirable design goal. This “ideal” power quality filter would exhibit three vital characteristics: efficient operation over a wide supply voltage range; total cancellation of residual surge voltage even in worst case instances; and certified endurance for over 1000 “worst-case” surges.
