APPARATUS FOR CONTROLLING POWER CONVERTERS

摘要

In an apparatus for controlling switching operations of switching elements of a power converter to convert input power to output power, a drive controller is configured to generate a drive control instruction indicative of predetermined switching operations of the switching elements, and output the drive control instruction. A driver is configured to drive, in accordance with the drive control instruction, the switching elements, so that the switching elements perform the predetermined switching operations. A switching speed adjuster is configured to obtain at least information indicative of atmospheric pressure, and adjust a switching speed of each of the switching elements such that the switching speed of the corresponding switching element decreases with a decrease of the atmospheric pressure.
