“…Pulse generators equipped with semiconductor switches in series configuration [85] or in Marx configuration [86], low-scatter spark gap switches in self-breakdown mode [87], and spark gap switches triggered by a semiconductor-based trigger generator [88] are in use and under continuous development. For parallel configuration of Marx generators, over-voltage triggering enables long-term operation of spark gap switches without additional wear [89].…”

Offshore wind farms are rapidly growing owing to their comparatively more stable wind conditions than onshore and land-based wind farms. The power capacity of offshore wind turbines has been increased to 5MW in order to capture a larger amount of wind energy, which results in an increase of each component's size. Furthermore, the weight of the marine turbine components installed in the nacelle directly influences the total mechanical design, as well as the operation and maintenance (O&M) costs. A reduction in the weight of the nacelle allows for cost-effective tower and foundation structures. On the other hand, longer transmission distances from an offshore wind turbine to the load leads to higher energy losses. In this regard, DC transmission is more useful than AC transmission in terms of efficiency because no reactive power is generated/consumed by DC transmission cables. This paper describes some of the challenges and difficulties faced in designing high-power-density power conversion systems (HPDPCSs) for offshore wind turbines. A new approach for high gain/high voltage systems is introduced using transformerless power conversion technologies. Finally, the proposed converter is evaluated in terms of step-up conversion ratio, device number, modulation, and costs.

“…The topology uses only four controlled switches per cell [7], the reduce number of switches by cell is an industrial advantage, in comparison to the normal 5 and 6 switches solid-state based bipolar Marx [8]. Of course, the cost of fewer devices is the heavy duty-cycle on the semiconductors but with optimize operation condition the losses can be reduced, mainly the switching losses.…”

The preliminary results from a bipolar industrial solidstate based Marx generator, developed for the food industry, capable of delivering 25 kV/250 A positive and negative pulses with 12 kW average power, are presented and discussed. This modular topology uses only four controlled switches per cell, 27 cells in total that can be charged up to 1000V each, the two extra cells are used for droop compensation. The triggering signals for all the switches are generated by a FPGA. Considering that biomaterials are similar to resistive type loads, experimental results from this new bipolar 25 kV modulator into resistive loads are presented and discussed.
