摘要： A circuit that may control current to a load without generating a large amount of electromagnetic interference on main lines of an AC power supply for the load and circuit. Control may be effected with silicon controlled rectifiers (SCRs). For instance, the circuit may implement passive triggering using a capacitor between the anode and the gate of an SCR. By using a sufficiently large capacitor, gate current may be applied during a zero crossing of a waveform of the AC power supply in a passive manner without a need to store energy prior to the zero crossing. The circuit may synchronize SCR triggering with a voltage variation in a clean manner, that is, without generating electromagnetic interference. The circuit may be used with an in-line thermostat. However, the circuit may be used in other ways.
