The capacitor performs three functions simultaneously: it stiffens the DC bus voltage against transient drops during switching; it absorbs the ripple current generated by the difference between the continuous source current and the pulsed inverter current; and it provides hold-up.
It integrates the photovoltaic, wind energy, rectifier modules, and lithium batteries for a stable power supply, backup power, and optical network access in one enclosure.
The production version of the 2009 i-MiEV has a single mounted on the rear with a rated peak power output of 49 kW (66 hp) (between 2500 and 8000 RPM) and torque output of 180 N⋅m (130 lbf⋅ft) (between 0 and 2000 RPM). The continuous power rating is 35 kW (47 hp). The North American model had a rated stall torque output of 197 N⋅m (145 lb⋅ft) (between 0 an.
