“…Thus, there is more and more demand for high step-up DC-DC converters, and lots of research has been carried out on this topic. Many other industrial applications, such as TV-CRTs, X-ray systems, auxiliary power supplies for electrical vehicles, high-intensity discharge (HID) lamps for automobiles, also require dc/dc converters with high step-up voltage conversion ratio [3,4].…”

Aiming to integrate the respective merits of the switched-capacitor converter and the quasi-Z-source converter. An novel high step-up quasi-Z-source DC-DC converter with a single switched-capacitor branch is proposed. Compared to other high boost DC-DC converters, the proposed converter can provide higher output voltage gain, lower current stress across the switches, and lower voltage stress across the output diodes by using the same or similar passive and active components. Therefore, the efficiency and reliability of the converter can be improved. The topological derivation, operating principle, parameter selection, and comparison with other DC-DC converters are presented. Finally, both simulations and experimental results are given to verify the characteristics of the proposed converter.

“…However, the current stress is high and the voltage stress of the diode in the last stage is equal to the high output voltage leading to more losses. In [9][10], switched-capacitor-based boost converters with only one switch are presented. In these converters not only the input current is continuous, but also the switch voltage stress is significantly reduced and the gain is increased.…”

-In this paper, a high step-up DC-DC PWM converter with continuous input current and low voltage stress is presented for renewable energy application. The proposed converter is composed of a boost converter integrated with an auxiliary step-up circuit. The auxiliary circuit uses an additional coupled inductor and a balancing capacitor with voltage doubler and switching capacitor technique to achieve high step-up voltage gain with an appropriate switch duty cycle. The switched capacitors are charged in parallel and discharged in series by the coupled inductor, stacking on the output capacitor. In the proposed converter, the voltage stress on the main switch is clamped, so a low voltage switch with low ON resistance can be used to reduce the conduction loss which results in the efficiency improvement. A detailed discussion on the operating principle and steady-state analyses are presented in the paper. To justify the theoretical analysis, experimental results of a 200W 40/400V prototype is presented. In addition, the conducted electromagnetic emissions are measured which shows a good EMC performance.

Drinking water can be purified by application of electric pulses across the water sample that has to be treated. Application of high Pulsed Electric Field (PEF) to the water kills the germs and the bacteria present and thus purify it. In this paper, a high voltage electric pulse generator module is proposed, which consists of boost converter and a capacitor diode voltage multiplier (CDVM) with a closed loop control on its output voltage. A low voltage DC source is used at the input and the output of the module will be a pulsed output voltage. The proposed generator is validated by simulation study.
