Through three-winding coupled inductors, a high step-up conversion with high efficiency is obtained. The proposed converter not only reduces the current stress, but also constrains the input current ripple, which decreases the conduction losses and lengthens the life time of input source. In addition, due to the lossless passive clampperformance, leakage energy is recycled to the output terminal. Hence, large voltage spikes across the main switches are alleviated and the efficiency is improved. Even, the low-voltage stresses on semiconductor components are substantially lower than the output voltage. Finally, the prototype circuit with input voltage 48 V, output voltage 380 V, and output power 2 kWis operated to verify its performance. The highest efficiency is 96.5%, and the full-load efficiency is 92.6%.

In addition, the extreme duty cycle may result in a serious reverse-recovery problem and conduction losses. A flyback converter is able to achieve high step-up voltage gain by adjusting the turns ratio of the transformer winding. However, a large voltage spike leakage energy causes may destroy the main switch. In order to protect the switch devices and constrain the voltage spike, a high-voltage-rated switch with high on-state resistance (RDS-ON) and a snubber circuit are usually adopted in the flyback converter, but the leakage energy still be consumed. These methods will diminish the power conversion efficiency. In order to increase the conversion efficiency and voltage gain, many technologies such as zero-voltage switching (ZVS), zero-current switching (ZCS), coupled inductor, active clamp, etc have been investigated. Some high step-up voltage gain can be achieved by using switched-capacitor and voltage-lift techniques, although switches will suffer high current and conduction losses. In recent years, coupled-inductor technology with performance of leakage energy recycle is developed for adjustable voltage gain; thus, many high step-up converters with the characteristics of high voltage gain, high efficiency, and low voltage stress have been presented. In addition, some novel high step-up converters with three-winding coupled inductor have also been proposed, which possess more flexible adjustment of voltage conversion ratio and voltage stress.

A boost converter (step-up converter) is a DC-to-DC power converter with an output voltage greater than its input voltage. It is a class of switched-mode power supply (SMPS) containing at least two semiconductors (a diode and a transistor) and at least one energy storage element, a capacitor, inductor, or the two in combination. Filters made of capacitors (sometimes in combination with inductors) are normally added to the output of the converter to reduce output voltage ripple.

Therefore, lithium iron phosphate can be an excellent candidate for secondary source to react to fast dynamics and contribute to load peaking. The proposed converter with fuel cell input source is suitable to operate in continuous conduction mode (CCM) because the discontinuous conduction mode operation results in large input current ripple and high peak current, which make the fuel cell stacks difficult to afford. The proposed converter employs a switched capacitor and a voltage-doubler circuit for high step-up conversion ratio. The switched capacitor supplies an extra step-up performance; the voltage-doubler circuit lifts of the output voltage by increasing the turns ratio of coupled-inductor.

The electrical specifications is shown in Table I. The design consideration of the proposed converter includes components selection and coupled inductors design, which are based on the analysis presented in the previous chapter. In the proposed converter, the values of the primary leakage inductors of the coupled inductors are set as close as possible for current sharing performance. Due to the performances of high step-up gain, the turns ratios can be set as 1 for the prototype circuit to reduce cost, volume, and conduction loss of windings. Thus, the copper resistances which affect efficiency much can be decreased.
