Abstract:
An electrical circuit and method for use in suppressing source and load-side transients appearing on a power-supply line. The circuit includes a high-speed clamping stage, a high-energy clamping stage, and a highly efficient LC filter for dissipating harmonic voltage and current caused by clamping the transient. A third clamping stage may be included so as to provide for common-mode suppression.
