Abstract :
The suppression of conducted EMI emissions of a Buck-boost converter using a gate controlled circuit is presented. The results indicate that the conducted EMI could be suppressed by controlling the rise and fall time of the gate signal when using a MOSFET as a switching device. The simulated results of the Buck-boost converter at a 100 kHz switching frequency are compared with the experimental results.
