Todays, the pulsed power systems have been employed in many applications. To meet the requirement of user, the pulse generator should enjoy the advantages of compactness, high flexibility, high pulse repetition rate and cost efficiency. Among all of converters that can be used to generate high voltage pulses, capacitance diode voltage multiplier (CDVM) is a good candidate to meet the mentioned requirements...
The self-consumption of PV-systems can be increased with a battery. The proposed three-phase inverter provides three independent DC inputs that can each be connected to a battery or a PV-string. The innovative topology allows energy flow in each direction at a very high efficiency (> 98 % in each converter stage). The application of SiC transistors leads to a higher switching frequency (48 kHz)...
For utility-scale photovoltaic (PV) power plants, the trend goes towards larger installations with reduced levelized costs of electricity. Further cost reductions can be achieved by modular and redundant inverter topologies, which enable higher reliabilities and a better overall system availability. In this paper, a comparative evaluation of selected three-phase single-and multi-stage voltage source...
The new configuration proposed in this paper for Marx Generator (MG.) aims to generate high voltage for pulsed power applications through reduced number of semiconductor components with a more efficient load supplying process. The main idea is to charge two groups of capacitors in parallel through an inductor and take the advantage of resonant phenomenon in charging each capacitor up to a double input...
A new pulsed-power generator based on a Marx generator (MG) is proposed in this paper with a reduced number of semiconductor components and with a more efficient load-supplying process. The main idea is to charge two groups of capacitors in parallel through an inductor and take advantage of the resonant phenomenon in charging each capacitor up to twice as the input-voltage level. In each resonant...
The configuration proposed in this paper aims to generate high voltage for pulsed power applications. The main idea is to charge two groups of capacitors in parallel through an inductor and take the advantage of resonant phenomena in charging each capacitor up to a double input voltage level. In each resonant half a cycle, one of those capacitor groups are charged, and finally the charged capacitors...
Photovoltaic (PV) inverters convert the DC current of solar generators into AC current and feed it into the grid. There are three basic inverter topologies: inverters with low frequency (50/60 Hz) transformer (LF), inverters with high frequency transformer (HF) and transformer-less inverters (TL). The European market is dominated by transformer-less types (80%), in Japan approx. 50% of the inverters...
