Abstract
For renewable sources application like smart grids, microgrids, etc. high voltage gain converter becomes a fundamental unit. In this article, a new hybrid circuit of zeta and boost converter based on active-quad-switched-inductor (AQSL) is proposed. The discontinuous input current in classical zeta circuit determines the less consumption of input source. However, the proposed hybrid zeta-boost converter provides a higher voltage gain with continuous input and output currents. It achieves higher voltage gain devoid of the high-frequency transformer, and multiple stages of diode and capacitor circuit. The mode of operation, boundary region, and non-ideal model of the proposed converter are presented. Design consideration and a comparison study with recent circuits are provided. The design circuitry of the proposed converter investigated and the functionality of the suggested circuit is validated.
Highlights
Nowadays, DC-DC converter circuits are gaining more popularity in the renewable energy system [1]; since the basic boost converter circuits does not provide expected characteristics in terms of voltage gain [2]
Conventional converters appear inappropriate for high voltage gain applications as an increment in duty ratio leads to the degradation in performance of converter in the form of rising conduction losses, decimating the voltage gain and its performance
This article proposes a new hybrid converter based on zeta converter, boost converter, an active-quad-switched-inductor (AQSL) structure for high voltage gain
Summary
DC-DC converter circuits are gaining more popularity in the renewable energy system [1]; since the basic boost converter circuits does not provide expected characteristics in terms of voltage gain [2]. Bhaskar et al.: New Hybrid Zeta-Boost Converter With Active Quad Switched Inductor for High Voltage Gain have been applied to enhance the output voltage [18], [19]. The XY converter family provides high voltage gain; discontinuous input current, switch voltage, and capacitor stack is a major drawback [11]. This article proposes a new hybrid converter based on zeta converter, boost converter, an active-quad-switched-inductor (AQSL) structure for high voltage gain. The circuit is designed by combining zeta and boost converter, active quad switched-inductor (AQSL). The current through diodes of boost converter, i.e. DB1, DB2, DB3, and DB for time period (t2 to t3) is as follows, iDB1 = iDB2 = iDB3 = iDB = 0. From (42), the DCM voltage gain is expressed as, VM ,DCM
