本文介绍了E类放大器在负载电阻变化时仍能保持正常工作的离散控制方法的概念。在所提出的方法中，通过设置连接到电容的开关的状态，以电子方式改变并联电容和输出谐振电容。所提出的方法可以保持标称操作，即，当负载电阻高于设计值和低于设计值时，均为ZVS和ZDS。PSIM仿真验证了所提出的电路的操作。
This paper introduces concept of discrete control method of class E amplifier which keeps nominal operation for varying load resistance. In the proposed method, shunt capacitance and output resonant capacitance are varied electronically by setting status of switches which are connected to capacitances. Proposed method can keep nominal operation, i.e., ZVS and ZDS, both when load resistance is higher than the designed value and lower than the designed value. Operation of proposed circuit is verified with PSIM simulation.
