Ten different modulation methods of the isolated quasi Z-source inverter based DC-DC converter were tested to find out radiated emission levels. EMC measurements were performed on a low power 250 W prototype. A radiated emission test was carried out in a GTEM cell (gigahertz transverse electromagnetic cell) according to the EMC standard IEC 61000- 4-20. To obtain a complete overview of the emissions, both C and D bands were included in a single test at the start and stop frequencies 30 MHz and 1 GHz, respectively. Measuring bandwidth of 120 kHz with a 6 dB EMI filter was used.
