The main objective of this paper is three-fold. First, to provide an overview of the current status of the power electronics technology, one of the key actors in the upcoming smart grid paradigm enabling maximum power throughputs and near-instantaneous control of voltages and currents in all links of the power system chain. Second, to provide a bridge between the power systems and the power electronic communities, in terms of their differing appreciation of how these devices perform when connected to the power grid. Third, to discuss on the role that the power electronics technology will play in supporting the aims and objectives of future decarbonized power systems. This paper merges the equipment, control techniques and methods used in flexible alternating current transmission systems (FACTS) and high voltage direct transmission (HVDC) equipment to enable a single, coherent approach to address a specific power system problem, using 'best of breed' solutions bearing in mind technical, economic and environmental issues.

“…As a typical controllable voltage source converter, the MMC offers significant advantages over the controllable switch converter, such as high modularity, low dv/dt, low switching frequency and power loss, and reduced current harmonics [3,6]. As a result, the MMC has been widely studied and applied in many medium-and high-voltage applications [6][7][8], especially in VSC high-voltage DC (HVDC) transmission.…”

This paper proposes a novel hybrid multilevel converter with DC fault-blocking capability, i.e., the neutral-point clamped hybrid multilevel converter (NHMC). By employing two types of unipolar full-bridge submodules along with director switches, which are composed of seriesconnected insulated-gate bipolar transistors, the NHMC combines the features and advantages of the neutral-point clamped converter and the modular multilevel converter. The basic topology, operating principles, modulation scheme, and energy-balancing scheme of the NHMC are presented. The DC fault-blocking capability of the NHMC is investigated. The number of power electronic devices used by the NHMC is calculated and compared with other multilevel converters, showing that the proposed NHMC can be an economical and feasible option for medium-voltage DC transmission with overhead lines. Simulation results demonstrate the features and operating scheme of the proposed NHMC.

This paper proposes a method to extract the junction temperature of high-voltage and high-power P-i-N diodes. It is investigated that the swept-out charge during reverse recovery current fall time is affected by junction temperature variation, which makes the swept-out charge a possible thermo-sensitive electrical parameter (TSEP). Thanks to the specific package of high-power IGBT modules with P-i-N diodes, the swept-out charge of a P-i-N diode can be measured by the induced voltage v eE on the parasitic inductor L eE between Kelvin and power emitter terminals. In typical inductive half-bridge circuit, the comprehensive analysis of commutation between the upper P-i-N diode and lower enabled IGBT, discloses the monotonic relationship among the reverse recovery charge, reverse current fall time, and junction temperature. A double pulse chopper circuit is used to validate the theoretical analysis. The experimental results show that the dependency between diode junction temperature and charge during the reverse recovery current fall time is approximately linear. A 3-D look-up table is calibrated and can be used to estimate the P-i-N diode junction operating temperature. Finally, an experimental comparison of four TSEPs for P-i-N diode is presented to verify the feasibility of implementation of proposed TSEP.Index Terms -High-power P-i-N diodes, thermo-sensitive electrical parameter, reverse recovery charge, junction temperature extraction.I. .
