Since you now posted the service manual in your other thread, I can pretty much confirm that the inductor is for an active PFC/boost converter. On page 38:

In order to further improve inverter performance, control is switched between PWM control at low operation speeds, and PAM control at high operation speeds, making the most effective use of power.

At low speeds, the boost converter only operates as an active PFC and PWM is used to reduce the voltage to the motors. At high speeds, the boost converter increases the voltage to the inverter. Exactly like how the Prius inverter works.
