Ultraefficient Voltage Doubler Based on a GaN Resonant Switched-Capacitor Converter

Abstract: In this paper, we present a highly efficient and compact voltage doubler based on a resonant S'\\itched-capacitor converter implemented with GaN FF.Ts. Two possible approad1es for its implementation are analy:red and compared. In the first approach, the resonant inductor is placed in series with a resonant capacitor, conducting a sinusoidal current, while in the second, it is placed in series with the input source, conducting rectified sinusoidal current Roth resonant converters have the same voltage gain, and… Show more

“…Thus, the results go in accordance with the analysis in section IV and the calculated values in section V-B. and verified with simulation results, where the peak current amplitude and the inductance specifications are obtained from (27) and (34) respectively. When handling high-frequency AC currents, a key factor to the inductor design is choosing the right core material.…”

“…The figures show that high power factor and low THD are achieved with different input voltages, as the charge pump circuit works in the same manner. Yet, to achieve the full-load operation for the low line voltage, the resonant tank needs to be redesigned for the high current that will result from (27), while the current prototype was designed for the 230 V rms mains input as given in the design specifications in Table I. Even though the inherently achieved power factor and THD figures fall within the reported ranges, it is noted that the proposed solution has lower efficiency compared to several reported ones.…”
