[2] For use in space-rated systems, reliable hybrid circuits were developed to implement the ASDTIC function.
[3] The DC-DC converters under study in this work[4] had a similar form as a DC chopper or switching regulator.
A bipolar transistor switches current flowing into an L-C network of an inductor and capacitor.
The incoming signal is integrated over time and when it exceeds a threshold, a control pulse is generated by the ASDTIC.
[3] The ASDTIC control system of Schoenfeld & Yu was an attempt to improve this dynamic performance.
