Abstract
Magnetic compression switches are used in many applications to achieve high rates of rise of voltage and current that are not possible with other types of switches. However, magnetic switches are sensitive to charging voltage, reset current, and temperature, and changes in these variables can lead to poor performance or timing variations. As a method of output stabilization, some modulator systems use charge voltage as a closed loop feedback control variable. For systems that require large charge voltage variation, magnetic compression switches present problems in efficiency and timing. The use of computer control can overcome these problems and improve system performance significantly. By using a magnetic material that exhibits a non-square B-H loop, the volt-second product of a magnetic switch can be controlled with the reset bias current. Therefore, by properly selecting the reset bias current for a given charge voltage, an optimum switching time can be maintained over a wide range of charging voltages. The relationship of volt-second product to reset bias current is nonlinear, but this can be implemented easily in a microprocessor by creating a lookup table for every possible charge voltage.
