| Abstract |
An sliding method is proposed to control the inverter of an unbalanced UPS applying a voltage source mode. All phases can be regulated from a common strategy in asymetrical conditions, and the commutation decision is performed in real-time with a low-cost DSP.The PWM frequency is
adjusted through an adaptative hysteresis band, computed by the same DSP. Field Orientation theory and Park vector are used to synchronize the inverter to the utility and select the best semiconductor's status at any time. Some simulations are presented. |
