Abstract: Techniques are provided for controlling alternating current (AC) power which is supplied to an inductive load by an AC switch. For example, the AC power is controlled by a process which comprises detecting zero-voltage crossings of an AC voltage waveform of the AC power, monitoring a load voltage to detect for a presence of inductive flyback voltage when the AC switch is placed into a turned-off state, and determining a delay time to place the AC switch into the turned-off state subsequent to a detected zero-voltage crossing of the AC voltage waveform, when inductive flyback voltage is detected in the load voltage, so that the AC switch is placed into the turned-off state at a time which substantially coincides with a zero-current crossing of load current of the inductive load, to thereby suppress the generation of inductive flyback voltage when the AC switch is placed into the turned-off state.

Abstract: Intelligent electrical switches are provided to implement multi-way circuits using two or more intelligent electrical switches for controlling power to a load.
