Electrical system using phase-shifted carrier signals and related operating methods

An automotive drive system having an energy source, comprising:

• a three-phase motor driven by a first phase current signal (ia), a second phase current signal (ib) and a third phase current signal (ic), the three-phase motor, the motor comprising:
• a first set of windings each having a first magnetic polarity;
• a second set of windings each having a second magnetic polarity that is opposite the first magnetic polarity, the first set of windings being electrically isolated from the second set of windings;
• an inverter module coupled between the energy source and the motor, the inverter module comprising:
• a first set of phase legs each being coupled to a corresponding phase of the first set of windings,
• a second set of phase legs each being coupled to a corresponding phase of the second set of windings;
• and
• a capacitor coupled to the inverter module and the energy source, wherein the capacitor is electrically parallel to the energy source.
