Power electronics drive for cylcoidal electric machine

An electrical system includes a power inverter module (PIM) connected to DC and AC voltage buses and having a pair of inverter phase legs, at least one of which includes a plurality of semiconductor switche. A cycloidal electric machine with plurality of electrical phases is connected to the PIM via the AC voltage bus, and has a stator and a rotor with eccentric stator and rotor axes. The rotor moves with two degrees of freedom, including rotating motion about the rotor axis and orbiting motion about the stator axis. A controller applies, for each respective phase, a phase-specific offset value to a carrier signal and to a voltage reference signal. This generates a modified carrier signal and a modified reference signal, respectively, which in turn generate a pulse width modulation (PWM) signal. The electric machine is powered via the PIM by energizing the semiconductor switches using the PWM signal.
