Switching-Mode Power Supplies (SMPS) are often used to power on-board satellite payloads due to their good conversion efficiency. However, they emit radiated and conducted noise, which can disturb the operation of other payloads. The current ripple sum of the power supplies will appear on the power bus. There are many methods to reduce this summarized noise, one of them is to interleave the on-switching times of the converters. This ripple cancellation method can decrease the noise component on the switching frequency and on its upper harmonics. In this article we are going to demonstrate the noise cancellation method described above with a measurement platform consisting of two PWM controlled Buck controllers.
