Inverter — overview

The inverter is the brain of the system. It converts the battery’s direct current (DC) into sinusoidal alternating current (AC) in the motor windings.

By controlling amplitude, frequency and phase relative to the rotor’s position, the inverter makes the stator’s rotating magnetic field interact with the rotor’s permanent magnets. This interaction drives the motor and lets it be controlled precisely.

For the full design — specification, power calculations, DC-link capacitor sizing, the power stage and the proof of concept — see Inverter — design.
