Power electronics layout in a hybrid electric or electric vehicle drive system

Fault Diagnosis of Power Components in Electric Vehicles

“…As shown in Figure 5, power electronics in EVs are initially constituted by power switches and power elements [Vezzini, 1996;Zhu et al, 2008]. Open switch fault and short switch fault are the most common faults in power switches [Chau and Wang, 2005].…”

“…The major faults of electric motor are classified as the following [Benbouzid, 1998;Nandi et al, 2005 . Currently, the research mainly emphasizes on the study of controllable solid-state switches which are commonly found in the inverters and converters [Vezzini and Reichert, 1996;Masrur et al, 2010]. The major faults of power electronics are shown as follows [Masrur et al, 2010;Chau, 1996 In this paper, a review of the fault diagnosis in the core components of EVs is presented.…”

Power Electronics in HEVs

“…When the system is in the voltage closed-loop control mode, that is, V 2 = constant, then decreasing R L will result in the output power increasing since the output power is inversely proportional to R L as shown in Equation 9.52. To maintain V 2 as a constant, it can be seen from Equation 9.53 that D has to be adjusted accordingly: D(1 − D) ∝ 1/R L for a given V 1 .…”
