提出了一种新的DE类逆变器控制方案。该方法通过改变开关的导通和关断的驱动信号来产生输出电压和功率。该方案的优点是提高了低输出电压下的功率转换效率，工作在固定的工作频率，不需要扩大电路规模，适合控制宽的输出范围。进行了精确的分析和电路实验。结果表明，实验结果是非常相似的理论预测定性。在1.0 MHz 1.8 W输出下，效率超过93%。
A new control scheme for the class DE inverter is presented. This method generates the output voltage and power by varying driving signals which turn switches on and off. The advantages of the proposed scheme are the improvement of the power conversion efficiency for low output voltage, the operation at fixed operating frequency, unneccessity of enlargement of the circuit scale, and suitability for controlling the wide output range. An exact analysis and circuit experiments are carried out. It is shown that the experimental results are very similar to the theoretical predictions qualitatively. Measured efficiency is over 93% with 1.0-MHz 1.8-W output.
