The Z-source inverters are recent topological options proposed for buck–boost energy conversion with a number of possible voltage- and current-type circuit. This paper presents new step-up DC-DC converter topologies with improved efficiency, nearly twofold increased gain, over twofold boost factor and reduced ripple free output. The topology contains quasi ZSI (Impedance Source Inverter) which has one diode, two capacitors, two inductors are used to maintain continuous current on the primary side for reducing energy losses in the output, a single phase isolation transformer, and a voltage doubler rectifier (VDR). There are two operating modes shoot-through (ST) and non-shoot through (NST) modes. For controlling quasi ZSI (impedance source inverter), Pulse Width Modulation (PWM) with duty cycle ratio control method is used. By implementing the Simple boost control method of shoot- through technique is achieved in quasi ZSI (impedance source inverter), voltage boost factor and component stresses are considerably reduced when compared to the conventional method.

W artykule zaprezentowano nową topologię przekształtnika DC-DC o zwiększonej skuteczności, zmniejszonych tętnieniach. Zastosowano dwa tryby pracy: shoot-through ST i non shoo through (NST). W układzie zastosowano podwójny układ prostowania VDR. Do sterowania przekształtnika ZSI wykorzystano układ PWM.
