Abstract :
A simple bi-directional magamp control scheme is proposed. The scheme effectively reduces the influence of the time delay, or dead time of magamp core on the output voltage regulation at extreme load conditions. The scheme is very useful in the converters with magamp as post-regulator to eliminate the dead time of the magamp core due to the squareness of the core materials and to extend the load variation range
