Abstract
A lighting apparatus includes a lighting circuit (e.g., an LED lighting circuit) and a driver circuit having an output coupled to the lighting circuit and an input configured to be coupled to a power source, such as a phase cut dimmer, that provides a varying voltage waveform. The driver circuit includes an electromagnetic interference (EMI) suppression inductor configured to be coupled in series with the power source and a bypass circuit configured to divert current from the EMI filter inductor to limit a current in the EMI filter inductor.
