ELECTRONIC CONTROL DEVICE, ELECTRIC POWER STEERING DEVICE, AND VARIABLE TRANSMISSION RATIO STEERING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electronic control device capable of generating a requisite boosted voltage even if the supply voltage is heightened. SOLUTION: The electronic control device is equipped with an inverter to convert the DC voltage into an AC voltage by driving a switching element and a boosting means to boost the fed DC voltage into a voltage within the voltage range, in which the requisite voltage for driving the switching element is used as the lower limit value and the maximum voltage to be boosted is used as the upper limit value, and emit it to the inverter.
