Car motor driving apparatus

摘要

In a car body (1) provided with a battery (4) with a low output voltage of 12 V, a step-up circuit unit (5) is connected between the battery (4) and an electromechanical energy converting section (2). In a car (1) provided with a battery with a high output voltage of 36 V, the battery is connected directly to the electromechanical energy converting section (2).
