Abstract
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.<>
描述了一种用于空间应用的DC/DC变换器，其开关单元可以通过印制板上的两个跳线来改变。当最小化传导发射是主要要求，并使用航空电子总线(即28 V DC)时，将优先考虑升压加推挽配置;如果电压源要高得多，例如150 V DC，并且需要在宽频率范围内具有出色的音频敏感性，那么互补降压加推挽配置是最合适的。给出了两种开关变换器在z变换域的精确动态模型;实验频率响应图证明了它们与实际情况的良好吻合。
