This paper designs non-ferromagnetic reactor based on the concept of nullator and norator. Nullator and norator are used to equivalently represent Insulated Gate Bipolar Transistor (IGBT) device and to design voltage-reverse and current-reverse reactors of fixed frequency. According to IDBT´s characteristic that it can be equivalent to the fixed connection of nullator and norator, the equivalent transformation of voltage-reverse and current-reverse reactors is made and in this way principle circuit of voltage-reverse and current-reverse reactors of fixed frequency can be realized by the circuit consists of IGBT device. Thus voltage-reverse and current-reverse reactors in which only capacitors and IGBT devices are involved are designed. Simulation analysis is taken on Multisim. According to the simulation, phase angles of both reactors´ input current lag 90° behind phase angles of their input voltage, so voltage-reverse and current-reverse reactors meet the characteristics of reactors and they are able to replace ferromagnetic reactors in some fields.
