Megamp post regulators-practical design considerations to allow operation under extreme loading conditions

摘要

Practical design equations and guidelines are established to allow magnetic amplifier (magamp) operation under extreme loading conditions. Three conditions are considered: shutdown of output, foldback of the output current, and operation under discontinuous inductor current mode. Design equations are derived for the three extreme operations, and their use is illustrated by numerical examples. The design equations provide the designers with tools for parameter trade-offs and lend themselves to computer-search design procedures.
