Abstract
The design of a high-frequency, multimodule boost regulator suitable for use as a spacecraft battery discharger is presented. A combination of AC inductor current feedback and current-injection (DC switch current feedback) is used for optimum dynamic performance, overload protection, noise immunity, and current sharing of the modules. By suitable design of the second stage output filter, it is shown that the output impedance characteristic possesses a resonant notch instead of a resonant peak and can ensure system stability over a wide range of complex load conditions. Both the overall loop gain and the outer loop gain must be viewed to fully understand all system dynamics.<>
