Solving Unique Challenges Inherent in HEV/BEV

The advent of high voltage DC power busses in hybrid and full electric vehicles (HEV/BEV), as well as the continued electrification of previously crank driven accessories such as vehicle HVAC, steering, brakes, and active suspension systems, brings some unique testing challenges. In particular, specifying and acquiring compact, high voltage (200 Vdc to 600 Vdc), high current sources capable of providing fast slew rate transient test signals is a potential product development bottleneck.
