calculation in real time, and builds the PWM references for the inverter. It is
another processor, a microcontroller, which handles all digital input/output
(including the command of the PWM inverter). More dedicated to control than
to calculations, this microcontroller ensures for instance the closing of relays
and contactors.
One control unit may command up to 8 power modules.
