A power supply uses first and second saturable reactor means connected to receive complementary first and second input voltages. The first saturable reactor means is disconnected from the first input voltage when the second saturable reactor means is connected to the second input voltage and vice versa. The power supply includes structure for sensing a variation in the power supply output voltage from a desired value and for producing a control signal in response thereto. A signal representative of volt-seconds, generated in a feedback path, is passed through both first and second saturable reactor means to adjust the flux in the particular saturable reactor means not connected to its input signal. This sets the initial flux in that saturable reactor means the next time it is connected to its input voltage. A change in the power to be supplied by the power supply causes a change in the time necessary to saturate each of the two saturable reactors. The two saturable reactors are connected and disconnected to their corresponding input voltages on a periodic basis. The system is capable of responding to changes in demand for this power within one-half period of switching between said first and second saturable reactors.
