| Abstract: | Based on linear power amplifier technology,a DC/AC converter was designed,which was comprised of control circuit and linear amplifier.In this converter,2nd-order filter,amplitude stabilizer and linear power amplifier were adopted to realize conversion from 500 Hz square-wave input to 500 Hz sine-wave output.Test results show that the converter features small distortion in output waveform and high stability in output amplitude. |
