A New Triple-Switch-Triple-Mode High Step-Up Converter With Wide Range of Duty Cycle for DC Microgrid Applications

Abstract: DC microgrid is gaining attraction and a recent trend in distribution power generation system due to penetration of renewables (especially Photovoltaic (PV) or Fuel Cell (FC)). In this paper, a new Triple-Switch-Triple-Mode High Step-Up converter (TSTM-HS converter) is presented for DC microgrid applications. In the proposed converter, voltage lift technique is employed and range of duty cycle is extended by incorporating an additional switch in converter circuitry. By doing this, high voltage conversion ratio… Show more

“…In order to step-up the voltage or current with high gain, DC-DC power converters are essential in case of many applications e.g. photovoltaic and fuel cell energy conversion, uninterruptible power supply, DC microgrid, automobile, high intensity discharged lamp ballast, LED, hybrid vehicle, etc., for the utilization of low voltage sources [2]- [3]. As far as the conventional boost converter is concerned, theoretically, it provides a high voltage gain at a duty cycle value closer to unity.…”

“…High voltage gain non-isolated converters without coupled inductors exhibit a simpler structure, being more suited for low power level applications [20][21][22][23][24][25][26][27][28][29][30][31]. In Ref.…”

“…The series/parallel combination of the photovoltaic (PV) panels is not a viable solution to increase the voltage/current due to the requirement of large space and cost [2]- [4]. Thus, the DC-DC converter with a high gain voltage conversion ratio is required to achieve high voltage outputs [5]. Several DC-DC converters are addressed and achieved high voltage by using several inductors and capacitors combinations with increased parasitic losses and bulky in size [6]- [7].…”
