Abstract This chapter first introduces the application of four-quadrant converter and the problems it leads to. Secondly, this paper introduces the working principle of four-quadrant converter, including the two-level four-quadrant converter main circuit, switching function, the principle of SPWM modulation, and transient current control. Through introducing the working principle of the four-quadrant converter, the grid-side harmonic characteristics of four-quadrant converter are analyzed. Theoretical analysis and simulation verify the influence of operating conditions, power, network voltage and the circuit topology on harmonics of four-quadrant converter respectively. The influence factors of four-quadrant converter harmonics and their effects are summarized at last.
