Abstract:This paper introduces a voltage follower type of supply hybridized by the switch filter unit with the linear unit,analyzes the principle of the composition,the topology of Switch Linearity Hybrid(SLH) power converter.The theory analysis,simulation and experimental results show that the SLH power converter possesses the characteristics of high efficiency,low THD,the capacity suitable to varied kinds of loads(including non-linear load) and resistance load disturbance.
