摘要
介绍了一类由开关放大电路与线性放大电路复合而成的电压跟随器型电源,这种电路具有线性电路与开关放大电路两者的优点,还分析了其构成原理,提出了选择开关单元与线性单元的原则。理论分析、仿真和实验结果表明它具有高效与优波兼顾的特性,以及适应多类负载(含非线性负载)和抗负载扰动的能力,因此在电力电子变换器中具有广泛的应用。
A voltage follower type of supply hybridized by the switch amplify unit with the linear unit was introduced, which acquire their synthetic optimal performances. Analyzed the principle of the composing, gave the fundamental of choosing the switch amplify unit and linear unit. Theory analyses, simulation and experi- mental results show that the switch linearity hybrid（SLH） power converter possess the character of high efficiency, low THD, the capacity suitable to varied kinds of loads（including nonlinear load） and resisting load disturbance,so SLH converter has a prospect future in power converters.
