Voltage multiplier factor circuits area unit wide employed in several high-voltage/low-current applications this paper proposes a hybrid SVM (HSVM) for dc high-voltage applications. The multiplier factor is made by cascading a diode-bridge rectifier associated an (symmetrical voltage multiplier factor) SVM with diode-bridge rectifier because the initial stage of multiplier. The planned topology saves 2 high-voltage capacitors and needs just one secondary of HVT. Besides, it's lesser free fall and quicker transient response at start-up, compared with typical SVM.

Series Z-Source network, Associate in Nursing enlargement of the favored conception of Z-source dc link, was initially projected for enhancing the output voltage of power electronic inverters. Throughout this paper, that concept is extended on a three-phase indirect matrix converter. The converter depends on the ultra-sparse matrix topology characterized by the minimum vary of semiconductor switches. The series Z-source network is placed between the three-switch input rectifier stage and additionally the six-switch output electrical converter stage, in either the positive or negative rail. A short shoot-through state produces the voltage boost. Associate in Nursing optimum pulse breadth modulation technique is developed for higher boosting capability of the converter and reduce of switch losses. A comparison is made between the matrix converters mistreatment series and customary cascade Z-source networks. The inpouring current and Z-source capacitor's voltage are reduced inside the series Z-source matrix converter. [ABSTRACT FROM AUTHOR]
