Special Issue Information

Dear Colleagues,

Innovative, complex converter topologies, such as modular multilevel converters, are already widely deployed in HVDC and MVDC systems, where they offer reduced losses, increased controllability and efficiency, and significantly improved harmonic performance when compared to other converter topologies. However, research on wide bandgap semiconductor switches, advanced converter topologies, and control has shown that power electronic converters could also prove viable and advantageous for other high-power applications including large electrical drives, aerospace, and transport. This Special Issue invites articles that provide novel insights into the design, analysis, and control of new power electronic converters for high-power applications. Key topics include, but are not limited to the following:

  • New thyristor or transistor-based converter topologies
  • High-power switch transients and performance
  • Detailed study of converter operating modes, and thermal analysis
  • Fault-tolerant converter topologies and control strategies
  • Converters for high-power electrical drives, aerospace and transport applications, and their operation and control
  • HVDC and MVDC converters, and their operation and control

High-performance motor drives that operate in harsh conditions require an accurate and robust angular position measurement to correctly estimate the speed and reduce the torque ripple produced by angular estimation error. For that reason, a resolver is used in motor drives as a position sensor due to its robustness. A resolver-to-digital converter (RDC) is an observer used to get the angular position from the resolver signals. Most RDCs are based on angle tracking observers (ATOs). On the other hand, generalized predictive control (GPC) has become a powerful tool in developing controllers and observers for industrial applications. However, no GPC-based RDC with zero steady-state error during constant speed operation has been proposed. This paper proposes an RDC based on the second-order difference GPC (SOD-GPC). In SOD-GPC, the second-order difference operator is applied to design a GPC model with two embedded integrators. Thus, the SOD-GPC is used to design a type-II ATO whose steady-state angle estimation error tends to zero during constant speed operation. Simulation and experimental results prove that the proposed RDC system has better performance than other literature approaches. Full article
