Along with using renewable energy sources such as photovoltaic (PV), wind, and biomass, the power system structure has evolved and grown more complex in recent years. As a crucial part of power distribution, the three-phase converter plays a significant role; nevertheless, this does not account for the fact that various phase legs may experience different aging conditions. This study offers an active thermal control (ATC) concept for a two-level, three-phase, four-wire converter with balance circuit in order to delay the failure of the aged leg and the entire converter. The first ATC approach using the model predictive control (MPC) strategy is investigated to regulate the output current and balance the capacitor voltage. A modified cost function is proposed to improve the capacitor voltages balancing control capability. Additionally, the second ATC approach using a carrier-based pulse-width-modulation (CBPWM) method based per-phase voltage and current control is introduced. The achieved simulation and experiment results of both CBPWM and MPC schemes are presented to verify the performance of the ATC based per-phase power control for the two-level three-phase four-wire converter with balance circuit.
