High-gain switched-coupled-inductor boost converter
2009 International Conference on Power Electronics and Drive Systems (PEDS), 2009When a low voltage DC power source is used, a DC-DC converter with a high step-up voltage gain is required to raise the voltage to more applicable levels. This is typically achieved in classical converters which often have to be driven by pulse width modulation (PWM) waves with extremely high duty cycles.

High-Efficiency Bidirectional DC/DC Converter with High-Gain
2010 Asia-Pacific Power and Energy Engineering Conference, 2010A bidirectional converter for electromechanical brake/the recycling of power generation energy is proposed in this paper. The gain of the converter is high. Since the converter use the technique of passive lossless buffer and synchronous rectification, the main switches achieve the technique of soft switching.

High Gain Converters Based on Coupled Inductors and Gain Extension Cells
2021DC–DC boost converters with wide voltage conversion ratios are a crucial part of renewable energy systems. In this study, three different converter topologies based on coupled inductor (CI) are discussed. Converter-1 is a conventional boost converter (CBC) with a CI in the place of the simple inductor.

A Novel High Gain Bidirectional DC-DC Converter
2020 IEEE Industry Applications Society Annual Meeting, 2020The electric vehicle requires bidirectional DC-DC converter. A high conversion ratio is preferred to interface a low input battery voltage to the high voltage DC and vice-versa. A novel high gain DC to DC bidirectional switched converter is proposed in this paper. The proposed converter uses the interleaved technique to the input side so that the input
