    Abstract

    In this article a novel controllable reactor based on regulating the transformer's primary equivalent impedance by controlling its secondary voltage source inverter load is proposed. When the secondary current of a transformer is forced to be proportional to and in inverse phase with its primary current, the primary side of the transformer exhibits a linear adjustable reactance with respect to the proportion coefficient. The voltage source pulse width modulation (PWM) inverter connected to the secondary side of the transformer provides the required secondary current. In order to realise a large-capacity reactor, a transformer with multiple secondary windings is used to reduce the capacity requirement of each PWM inverter. A large-capacity (800 kVA) prototype is fabricated. The experimental results verify the characteristics of the novel controllable reactor - linear reactance tuning, few harmonics and fast response.
