<p>A reactive voltage regulator of the shunt type which effectively has a linear inductance in series between input and output terminals and has separate capacitive and inductive reactances shunting the output terminal. A bidirectional switch such as a triac is connected in series with the inductive reactance. The current taken by this inductive reactance, in a preferred embodiment, may be approximately twice that taken by the capacitive reactance such that selective phase angle firing of the bidirectional switch establishes this shunt composed of the capacitive and inductive reactance as selectively either capacitive or inductive in effect. By varying the firing angle of the switch, with respect to the voltage across the shunt regulator circuit, the output voltage or current may be regulated. Alternatively, the series linear inductance and the inductive reactance may be incorporated into a single leakage reactance transformer, and the entire reactive regulator has special advantages when operated on three phase.</p> |
