A new double-sampled delta-sigma modulator topology is proposed to relax the critical timing constraints in the modulator feedback path, thus the speed requirement of the quantizer and DEM logic can be greatly reduced. To verify the proposed modulator topology, a second-order double-sampled delta-sigma modulator was designed and simulated.
For non-thermal plasma technology corona discharge devices high-voltage, high-current pulses are used with very high demands considering rising voltage slopes. Many solid state pulse power modulator (SSPPM) system topologies are known however most include a high power transformer compromising the overall system efficiency. A modified Fitch generator topology is introduced enlarging the output voltage...
A broad circuit topology for bipolar or unipolar high-voltage repetitive pulse power applications is proposed. This circuit constitutes a merging version of the negative and positive solid-state Marx modulator concepts, which take advantage of the intensive use of semiconductor devices to increase the performance of the classic circuit. The flexibility of the proposed modular circuit enables the operation...
