Frequency and pulse width modulation for zero-voltage-switching resonant pole inverter

Abstract

The resonant pole inverter has the advantages of less component count and simple operation but the disadvantage is that the zero voltage switching can only be achieved for a very small load range. A new modulation technique is proposed to ensure the zero-voltage-switching to be maintained. Comparison of the proposed method to other modulations and inverters is presented. Theoretical and experimental results are shown.
