System of protection against electric shock for circuits with power electronics converters

Abstract

Modern low voltage circuits are very often equipped with power electronics converters, therefore in these circuits non-sinusoidal earth currents (touch currents) may occur. For non-sinusoidal currents safety criteria should be modified. This paper presents these modified criteria and a computer system of protection against electric shock which can be implemented in circuits with power electronics converters. The system is based on LabVIEW environment. Implementation of the safety system enables the disconnection of supply exclusively when real hazard of the ventricular fibrillation occurs.
