Model Predictive Control (MPC) offers many advantages over more traditional control techniques, such as the ability to avoid cascaded control loops. Unfortunately, as a result of the lack of presence of a modulation strategy, this approach produces spread spectrum harmonics which are difficult to filter effectively. Furthermore, high switching frequencies may be needed because of the limited number...
Nowadays the interest in active networks is significant as a result of to the larger penetration of renewable energy sources connected to the grid. In this scenario, multilevel power converters and, in particular, Cascaded H-Bridge converters allow the required flexibility and reliability to be considered as a building block for active nodes for the future electrical grid. The control of the power...
This paper focuses on new control techniques for a direct power converter having a resonant tank on the output side feeding a rectifier. The application being considered is for HV power supplies. The objective of the control is to provide a stable output, with good supply current quality. Two predictive controllers are described, one based on the output tank dynamics and one based on the input filter...
