| Abstract |
In this paper, the lossless inductor and transformer parasitic parameter-assisted high frequency zero
current soft switching (ZCS) inverter type DC-DC converter for the high voltage magnetron drive is
developed for industrial and consumer applications. The piecewise linear circuit model represented by
the measured v-i characteristics of the high voltage magnetron is considered for the converter analysis.
The high frequency transformer is inserted into the output port of the voltage source type full bridge
inverter because of the electrical insulation in addition to the output high voltage matching. A highly
efficient zero current soft switching DC-DC converter considering the magnetizing current of the high
frequency transformer is evaluated and discussed on the basis of simulation and experimental results.
Furthermore, the performances of the converter are evaluated by using the measured v-i database of
the power semiconductor device (IGBT) with anti-parallel diode and high frequency transformer
model are discussed on the basis of simulation and experimental data. |
