Motor drive apparatus, vehicle having the same mounted therein, and computer readable storage medium having a program stored therein to cause computer to control voltage conversion

摘要

A control device receives a power supply current from a current sensor and a reactor current from a current sensor and detects a maximum value and a minimum value from the reactor current and from the detected maximum and minimum values and the power supply current determines whether the reactor current traverses the zero point, and if so the control device generates and outputs a signal to an up converter which responds to the signal by stopping switching to perform an up or down converting operation.
