Harmonic current filters for single-phase triac switching circuits

Harmonic current filters for single-phase triac switching circuits

RL filters 178,180 are inserted in the supply conductors to reduce the level of harmonic currents flowing into the supply 172. The RL filters comprise a coil L51,L52 wound around a core in parallel with a resistor R51,R52.
