The constant power behavior of tight-speed controllers in the vehicle's traction system and tightly regulated DC-DC converters connected to the HV-DC bus produces instability effects. This paper proposes a simple and practical non-linear control, using Circular Switching Surfaces, to address constant power load instability in electric vehicle's power systems. The proposed control technique provides a solution in the geometrical domain to constant power loading conditions while achieving… CONTINUE READING
