Abstract

A multiplexing control apparatus (210) includes: three controllers (C) that output U-phase, V-phase, and W-phase analog voltage signals including U-phase, V-phase, and W-phase current command values for a motor (300), respectively; switches (SW1-SW3) provided for respective controllers (C) to switch the output lines to allow connection or disconnection; a U-phase intermediate value selection unit (211U) that receives U-phase output values of the switches (SW) and selects an intermediate value of the U-phase output values received; a V-phase intermediate value selection unit (211V) that receives V-phase output values of the switches (SW) and selects an intermediate value of the V-phase output values received; a W-phase intermediate value selection unit (211W) that receives W-phase output values of the switches (SW) and selects an intermediate value of the W-phase output values received; and a PWM output unit (212) that generates and outputs a PWM signal based on U-phase, V-phase, and W-phase intermediate values.
