CONTROL APPARATUS FOR AN ARCP INVERTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18520906 titled 'CONTROL APPARATUS FOR AN ARCP INVERTER
Simplified Explanation
The control apparatus for ARCP power inverters described in the abstract includes a modulator and a modulation control. The modulator is responsible for carrying out the commutation of the inverter using either Continuous PWM (CPWM) modulation or Discontinuous PWM (DPWM) modulation. The modulation control dynamically selects the appropriate modulation method to reduce switching losses and prevent commutation failure due to neutral point voltage unbalance.
- The control apparatus for ARCP power inverters includes a modulator and a modulation control.

Original Abstract Submitted
A control apparatus for ARCP (Auxiliary Resonant Commuted Pole) power inverters include a modulator and a modulation control. The modulator is configured to carry out a commutation of an ARCP inverter by selectively using a Continuous PWM (CPWM) modulation and a Discontinuous PWM (DPWM) modulation. The modulation control is configured to dynamically select either the CPWM modulation or the DPWM modulation in a such a way that switching losses of the ARCP inverter are reduced while a failure of the commutation of the ARCP inverter due to a neutral point voltage unbalance of the ARCP inverter is avoided.
