1. A motor control system comprising:
a voltage command module configured to determine a target d-axis voltage for an electric motor and a target q-axis voltage for the electric motor;
a target frequency module configured to:
selectively set a target switching frequency to a first predetermined switching frequency; and
selectively set the target switching frequency to a second predetermined switching frequency that is at least 2 kilohertz (kHz) greater than the first predetermined switching frequency; and
a switching module configured to:
based on the target d-axis voltage and the target q-axis voltage, determine target pulse width modulation (PWM) duty cycles for phases, respectively, of the electric motor; and
switch switches of legs of an inverter module connected to the phases of the electric motor at the target PWM duty cycles, respectively, and the target switching frequency.
