  1. Second, the results of theory analysis and simulation research show that the output of one cycle controlled bridge switching power amplifier have dc offset because of the nonideal characteristic of reset signal. the magnitude of output dc offset voltage is proportional to width of reset pulse. a voltage compensation technique is used to solve this question, and the computation formula of compensation voltage is gived. the circuit compensated and not are researched through simulation and experiment, which results show that compensated circuit solve the output dc offset effectively

    其次，理論分析和模擬研究結果表明，由於復位脈沖的非理想特性，單周控制的全橋開關功率放大器輸出端存在直流偏置問題，其大小與復位脈沖的寬度成正比。針對輸出直流偏置問題，提出了電壓補償的改進方案，給出了補償電壓的具體計算公式。對補償前和補償后的方案進行了對比模擬研究和實驗研究。
  2. At last, control circuit of one cycle controlled bridge switching power amplifier is improved with the basic idea of one cycle control. the simulation results show that the amplifier of improved control circuit not only solve the question of output dc offset, but also keep the voltage gain lowered by voltage compensation technique

    最後，根據單周控制的基本思路，改進了單周控制的全橋開關功率放大器的控制電路。模擬結果表明，改進控制電路后的系統不但解決了輸出直流偏置問題，而且解決了電壓補償方法所造成的放大器增益下降問題。
