Abstract

High-frequency resonant power converters are an attractive choice for high efficiency, high power density applications. Until recently, only resonant converters with 2 energy-storage elements have been studied and used for applications. However, some drawbacks of this class of converters can be overcome by the judicious augmentation of the resonant circuit. This paper presents the results of a study performed on two novel 4-element current-source resonant inverter circuits. These include analytical results on their steady-state characteristics (including input impedance, resonant frequency, input-output transfer function, component stresses, and efficiency). In addition, examples of design charts and experimental results are shown. They indicate that these resonant inverters have certain advantages over present ones.
两种新型四元电流源谐振逆变器的稳态特性
高频谐振功率变换器是高效、高功率密度应用的理想选择。直到最近,只有具有2个储能元件的谐振变换器被研究和应用。然而,这类变换器的一些缺点可以通过适当增加谐振电路来克服。本文介绍了两种新型四元电流源谐振逆变电路的研究结果。这些包括稳态特性的分析结果(包括输入阻抗、谐振频率、输入输出传递函数、元件应力和效率)。并给出了设计实例和实验结果。结果表明,谐振式逆变器与现有逆变器相比具有一定的优势。
