Abstract: A circuit for electromagnetic interference (EMI) reduction contains a signal input, a signal output, a pulse count controlling unit, a stand-by power reduction unit, a pulse series delay unit, and a temperature sensing unit. An alternating current (AC) input is provided to the signal input and the modified signal is drawn out from the signal output. The pulse count controlling unit and the pulse series delay unit modify the pulses of the pulse-width modulation process such that the overall efficiency of the circuit is increased. In particular, the pulse count controlling unit increases the number of pulses per cycle such that additional power is transferred onto the output load. On the other hand, the pulse series delay unit shifts the start time of a series of pulses such that the overall emission is reduced. The stand-by power reduction unit disconnects power when a circuit overload occurs.
