In this paper, a variable reactor suitable for voltage control of resistive loads is presented. The proposal gives the desired impedance variation using two naturally commutated thyristor switches in conjunction with three-limb magnetic circuit. Load voltage can be controlled by varying the thyristor firing angles and accordingly the DC flux level in the magnetic circuit. The effective impedance is smoothly varied with no need for external DC excitation. It is shown that the proposed voltage control method is accompanied by high power factor and lower harmonic content in the supply current. An equivalent circuit for the device is deduced from which analytical results are obtained. Theoretical and experimental results of a prototype are compared and shown to be of satisfactory agreement. |
