摘要

提出了一种二极管箝位线性放大器(DCLA)，用于实现开关操作引起的低电磁干扰。提出了一种新的DCLA概念，即更高效率的不等分压电源DCLA (DCLA- uedv)。在以往的研究中，推导出了最优电压比，在额定单位功率因数负载下，效率提高了1.7%。然而，除了在额定运行期间，还没有研究是否可以提高转换效率。在本研究中，分析了DCLA输出电压幅值和负载功率因数的变化。然后，明确了DCLA-UeDV相对于DCLA-eDV的优势工作区域。

Efficiency characteristics for changes in amplitude and power factor of diode-clamped linear amplifier unequally divided voltage power supply

A diode-clamped linear amplifier (DCLA) is proposed to realize low electromagnetic interference (EMI) caused by switching operations. A new concept of the DCLA, namely the higher efficiency unequally divided voltage power supply DCLA (DCLA-UeDV), is proposed. In previous studies, the optimal voltage ratio was derived, and a 1.7% points improvement in efficiency was realized for a rated unity power factor load. However, it has not been examined whether the conversion efficiency can be improved, except during the rated operation. In this study, operation of the DCLA is analyzed for changes in the amplitude of the output voltage and load power factor. Then, the advantageous operating region of the DCLA-UeDV against DCLA-eDV is clarified.
