A High Gain Bipolar Pulse Generator with Low Voltage Input Source

Abstract

This paper proposes a pulsed power generator which consists of two types of switched-capacitor booster modules. A doubling mode module employed to elevate the input voltage to a specified level and, constant mode module is used to increase the elevated voltage into the finally intended bipolar output voltage. Also, the proposed modular structure does not utilize any switches across the load. Other advantage of the proposed structure is its lower current stress on source and every circuit component near it. In comparison with Marx Generator (MG) based topologies, the number of circuit components has been significantly reduced, which led to cost-saving and prevention of circuit control complexity. Calculation of the capacitors is presented. Experimental tests and simulations are performed on a five-module system which confirms the high performance of the proposed topology.
