High Power Density Single Phase Inverter Using GaN FETS and Active Power Decoupling for Google Little Box Challenge Conference Paper

abstract

• 2015 IEEE. This paper presents a comparison between mitigation techniques for double line frequency ripples in single phase micro-inverters based on GaN FETs. A topology based on an auxiliary DC-AC stage is adopted based on optimizing both power density and efficiency to achieve the pressing needs for the next generation of micro-inverters as announced by Google's little box challenge. An accurate yet simple control algorithm is proposed that provides a ripple-free DC current. Experimental results demonstrate the effectiveness of the presented topology and control algorithm to achieve high power density micro-inverter rated at 2kW.
