A Comparative Study of Full-Bridge Inverter Based DVR and Semi-Z-Source Inverter Based DVR

摘要: There is always a necessity to protect the voltage sensitive industrial systems from Power Quality (PQ) issues prevent loss of product quality and revenue. Generally, custom power devices take responsibility mitigate these PQ problems, restore thus maintain standards. Dynamic Voltage Restorer (DVR) one among which offers an economical compensation load under abnormal supply conditions. The injected in series by DVR compensates profile during events; appropriate with protects restores pre-defined values. required generated inverter circuit system. most commonly used full-bridge consists four switches. Semi-Z-Source (SZS) based same injection capability only two-switches compared inverter. in-phase technique employed both DVRs for injecting into grid. efficiency, are studied. This paper presents simulation results MATLAB/Simulink environment validate thecomparison.
