Abstract
The single-phase T-type three-level inverter is firstly applied to the electric spring with switchable smart load,which reduces the harmonic content of the load voltage and a mathematical model of the T-type three-level electric spring with switchable smart load is established.And,the influence of the traditional carrier modulation on the mid-point potential of the T-type three-level electric spring with switchable smart load on the DC side is derived,and the control scheme of the mid-point potential is introduced,which combines with the integral separation control idea to obtain the control strategy of the T-type three-level electric spring with switchable smart load.The control strategy can effectively reduce the overshoot of the load voltage during the fluctuation of the grid voltage.Finally,it is verified by Matlab/Simulink simulation that the improved harmonic content is reduced by 3.47％and 1.65％,and the overshoot is reduced by 0.34％and 0.1％when stabilizing the critical and non-critical load voltages.关键词
