“…These spikes present values close to 30% of the output voltage of the converter. This data was necessary to compare this value with the design's reported output signal and define a limit value for the spikes on the converted inductor signal [37], [38]. Based on this comparison, it was established that this value might not overcome the 22% of the output voltage to guarantee a converter's continuous transition performance.…”

“…A switching-cell buck-boost MC [see Fig. 1(c)] is proposed in [21] with quasi-continuous input and output currents and no commutation issues. However, this uses four external diodes in addition to the six active switches, and has lower magnetic utilization.…”

“…4) The inductors suffer from higher current ripples Δi L (and magnetic flux density swings ΔB), which increase magnetic requirement and losses. Moreover, the buck-boost MCs in [20] and [21] have higher inductor current handing requirement of i in + i o , greatly increasing their winding losses (I 2 L r L ). To solve these above mentioned problems of existing buckboost MCs [19]- [22], this article proposes a highly efficient single-phase buck-boost MC, consisting of a small film capacitor, input, and output LC filters, and eight active switches.…”

“…The direct AC-AC converters are more attractive over the sizeable indirect AC-AC converters (AC-DC-AC converters) as their operation is accomplished through single-stage power conversion. They are the more viable choice in most applications, such as motor speed drive, grid voltage compensation [22][23][24], and induction heating systems [25,26]. Thyristor-based AC voltage controllers are used at the domestic level for speed regulation of the fans.…”
