A DC/DC converter for space applications is described whose switching cell can be varied by means of two jumpers on the printed board. When the minimization of the conducted emission is a primary requirements and the avionic bus (i.e. 28 V DC) is used, the boost plus push-pull configuration will be preferred; if the voltage source is much higher, for instance 150 V DC, and excellent audio susceptibility over a wide frequency range is required, then the complementary buck plus push-pull configuration is best suited. Exact dynamic models of both switching converters are given in the Z-transform domain; their good compliance with actual conditions is demonstrated by experimental frequency-response plots.
