Abstract

The adoption of wide-bandgap (WBG) switching devices in switching power converters provides several advantages, such as high power density, compact size and high efficiency, however a potential side-effect is the increased electromagnetic interference (EMI) due to high-speed switching transients. This paper presents an aperiodic modulation technique to suppress EMI in H-bridge based switched-mode power converters. A generic framework for the generation of an aperiodic carrier signal is demonstrated which can be extended and flexibly applied in other power converters. The aperiodic modulation strategy is programmed in a MATLAB Simulink environment and implemented using a field-programmable gate array (FPGA). The efficacy of the proposed aperiodic modulation was tested on a quasi-Z-source DC-DC converter, and a 10 dB suppression in the peak conducted EMI emissions was demonstrated.
