In this paper, the topology and the control scheme of the photovoltaic three-phase grid connected inverter based on voltage-oriented control (VOC) is analyzed. In VOC, a current control loop is used. The currents are controlled in a synchronous rotating dq-frame using a decoupled feedback control. The reference current of d-axis controller is extracted from instruction which comes from the former...
In this paper a PWM method for zero voltage switched three-phase isolated rectifier is presented. The presented PWM scheme features lower maximum output inductor current ripple and lower duty-cycle loss by more than half. Therefore, a smaller output inductor can be used and the ZVS operation can be extended at wider load range for MOSFET devices by increasing the leakage inductance of the transformer...
The bio-hydrogen producing process has complex interactions; thus, constructing a detailed mechanistic model and proper control architecture is difficult. Artificial neural networks (ANNs) are capable of inferring the complex relationships between input and output process variables without a detailed characterization of the mechanisms governing the process. This work presented a novel ANN that accurately...
