This invention relates to a power source for a nuclear fusion reactor for flowing a current to a load coil (e.g., a toroidal coil) provided in the nuclear fusion reactor such as a reversed field pinch apparatus comprising a bias power supply for supplying a current of a first direction to the load coil, and a reversed magnetic field power supply for supplying a current of a second direction reverse to the first direction to the load coil and having a circuit for holding the reverse current for a predetermined period of time, said bias power supply including a series circuit of a capacitor, a unidirectional element having a switching function and an inductor and connected in parallel with the load coil, thereby removing a clover element from the bias power supply. More particularly, according to this invention, when a current is flowed from the reversed magnetic power supply to the load coil, a current from the reversed magnetic power supply to the inductor in the bias power supply is stopped.
