Abstract：To meet the need of power battery testing, we design a charging-discharging device can be realized the bidirectional energy exchange of grid and battery. It have three interleaving bidirectional DC/DC converter and four quadrant rectifier based on SVPWM algorithm. Based on the output current harmonic analysis of time domain transformation, output harmonic offset the harmonic current harm from dead zone and grid voltage distortion, Experimental results show that the grid current harmonics and DC ripple of the charging-discharging device effectively restrain.
