Active switched‐capacitor based ultra‐voltage gain quadratic boost DC‐DC converters

Abstract: This paper presents active switched capacitor integrated ultra-voltage gain quadratic boost converters (ASC-QBC). The step-up conversion ratio provided by quadratic boost converter is not ample to meet the renewable microsource applications. The active switched capacitor integrated quadratic boost converter is a propitious alternate to acquire high voltage conversion ratios. A simple diode-capacitor voltage lift arrangement is used in one of the introduced converters, thereby further enhancing the voltage gain… Show more

“…Furthermore, with reference to Table 2, the proposed HQSU converter has lower voltage stress on its switches and diodes than other converters, including the converters in previous studies 27,28 ; consequently, the total voltage stress of the HQSU converter will be lower, as reflected in Figure 16. Despite having higher voltage gain, reduced voltage stress is one of the significant attributes of the proposed HQSU converter.…”

“…However, the converter 32 has less voltage gain than the proposed converter; in addition, the converter 32 has the drawbacks of pulsating source current and floating output. For an operating duty ratio of 0.8, the HQSU converter has a higher EI of 4.16 than other converters, except the converters 27,28 have an EI of 4.5.…”

“…[12][13][14][15][16][17] Modified quadratic gain converters with a gain of (1 + D)/(1 À D) 2 , where D is duty ratio, are reported in previous studies. 12,13,16 A converter with a gain of (3 À 2D)/(1 À D) 2 is reported in literature. 15,16 This quadratic gain converter can achieve a higher voltage gain only when the duty ratio D > 60%.…”
