“…Conventionally employed voltage‐fed and current‐fed converters with high transformer turn ratios are not well suited for high step‐up applications. A higher transformer turn ratio often results in larger transformer size, larger leakage inductance, a more complicated transformer design and so on, which may cause high voltage stress on diodes and output capacitors and lower switching frequency [5–9]. Voltage doubler rectifiers, such as half‐wave and full‐wave voltage doubler rectifiers are better choices for high step‐up applications because its output voltage is twice of the voltage in secondary winding of the transformer.…”

“…Therefore, the voltage doubler rectifiers such as half-wave and full-wave voltage doubler rectifiers are better choices for high step-up application because its output voltage is twice that of the transformer secondary winding. Accordingly, the transformer turn ratio can be halved [5][6][7][8][9][10][11][12][13][14][15][16]. This paper proposes a novel 4-times voltage multiplier rectifier for high step-up converters.…”

A novel 4-times voltage multiplier rectifier with smart Time-Division-Multiplexing (TDM) control strategy for high step-up converters is proposed in this paper. Based on the proposed TDM control strategy, two full-wave voltage doubler rectifiers can be combined to realize the proposed 4-times voltage multiplier rectifier. The novel 4-times voltage multiplier rectifier and TDM control strategy can reduce transformer turn ratio and transformer size for high step-up converters and also reduce voltage stress for the output capacitors and rectifier diodes. Simulations and experiments are conducted in this paper to validate the proposed 4-times voltage multiplier rectifier with smart TDM control strategy for high step-up converters. The results show that the proposed smart TDM control strategy has great potential to be used in high step-up converters.

“…On the other hand, the diode voltage stress is much higher than the high output voltage. Therefore, the switching frequency of the converter is limited and the efficiency is reduced due to the relative poor switching characteristics of the high voltage-rated diodes [12,13].…”

An advanced symmetrical voltage quadrupler rectifier (SVQR) is derived in this paper to serve as the secondary rectification topology, which helps to extend the converter voltage gain and reduce the output diode voltage stresses. The output voltage is four times of the conventional full-bridge voltage rectifier with the same transformer ratio, which benefits to reduce the turns ratio of the transformer and decrease the parasitic parameters. Also low voltage-rated diodes with high switching performance can be applied to improve the efficiency. Meanwhile, all the diodes in SVQR have the same voltage and current stresses, which simplifies the thermal design. Furthermore, two output electrolytic capacitors are connected in series to share the high output voltage, and the voltage balance can be realized naturally without any additional voltage-sharing scheme. A clear picture is made in this paper to give a general framework and universal applications for the derived SVQRs for high step-up and high output voltage conversion systems. A dual boost converter is used as an example to demonstrate the clear advantages of the derived symmetrical voltage quadrupler rectifiers (SVQRs).Index Terms -Boost, High step-up, Symmetrical voltage quadrupler rectifier. .
