The inverter required in electric powertrains causes a ripple on the entire DC-bus due to the switching of the transistors. This ripple can negatively affect the lifetime of a battery or alter the inner resistance and therefore also the battery's efficiency. . Ripple, where does it come from ? An perfectly wired installation will under full load give a ripple of +/- 0,6 to 0,8 volt. • Due to ripple during charging the charge power is reduced. What are the concerns? Ripple voltage and the resulting. . Fast-switching semiconductors induce ripple currents on the high-voltage DC bus in the electric vehicle (EV).
