An inverter controller is used to control an inverter circuit that drives an electric motor including a rotor and a stator. The inverter controller includes a voltage detector configured to detect input voltage, a current detector configured to detect motor current, an instruction value calculation unit configured to calculate an instruction value based on an external instruction value and a detection result of the current detector, a correction unit configured to calculate a corrected instruction value by correcting the instruction value in accordance with the input voltage, a PWM control unit configured to control the motor current based on the corrected instruction value and the input voltage, and a position estimation unit configured to estimate a rotation position of the rotor based on the instruction value and the detection result of the current detector.
