摘要:A majority of small-scale renewable energy sources including the solar PV modules, fuel cells gives out output voltage in the range of around 15–40 V DC. This needs to be stepped up to suit load requirements using a high voltage gain converter. Since renewable sources inhere...

摘要:... Conventional services tendered to provide network support rely on the availability of synchronous generation and because of this, future power system operators will have to develop new ways to obtain the ancillary services required. A technology rapidly gaining in popularity ...

摘要:A thorough comparison of the transient behaviours of two state-of-the-art converters suitable for HVDC transmission is presented. The alternate arm and mixed-cell modular multilevel converter topologies both have DC fault blocking capability and are selected for the comparison. C...

摘要:A three-phase interleaved (LC)(L)-type dc–dc series-resonant converter with a capacitive output filter using fixed frequency control is proposed. The converter operations for different modes during different intervals have been presented using the operating waveforms. The co...

摘要:This paper proposes a solution to complement the insufficient voltage gain and voltage stress distribution of classical interleaved boost converter in high step-up application. An interleaved converter integrating coupled inductor and voltage multiplier cell, which provides an ad...

摘要:For a DC grid using modular multi-level converters (MMCs) fast control of the DC bus is an important requirement. A control design is presented where a sudden DC voltage drop is compensated without any influence on the AC side. Using a suitable pattern in the MMC internal circula...

摘要:... There are some problems from the direct current–direct current (DC–DC) converter of high power marine transmitter, the load is light, when the output current is relatively small, the lagging-leg switching cannot easily achieve the zero voltage switching (ZVS), and the ...

摘要:The study proposes the application of state variable and cyclic-averaging modelling techniques for analysis of bidirectional, dual active bridge, CLLC resonant converters. The techniques are applied for converters operating under single phase-shift modulation in forward and rever...
