2. Abstract
• This project proposes a novel isolated high step-up converter for sustainable energy applications.
Through an adjustable voltage-multiplier module, the proposed converter achieves a high step-up
gain without utilizing either a large duty ratio or a high turns ratio.
• The voltage-multiplier modules are composed of coupled inductors and switched capacitors. Due
to the passive lossless clamped performance, leakage energy is recycled, which alleviates a large
voltage spike across the main switches and improves efficiency.
• Thus, power switches with low levels of voltage stress can be adopted for reducing conduction
losses.
• In addition, the isolated topology of the proposed converter satisfies electrical-isolation and
safety regulations.
• The proposed converter also possesses continuous and smooth input current, which decreases
the conduction losses, lengthens life time of the input source, and constrains conducted
electromagnetic-interference problems.

4. Existing System
• Many isolated step-up converters without continuous and smooth input current levels result in
conducted electromagnetic-interference (EMI) problems.
• Thus, a bulky input filter must be designed in order to meet safety regulations.
• Moreover, such isolated step-up converters need more complex pulse-width modulation (PWM)
control, which increases cost and decreases reliability.

5. Proposed System
• The proposed high step-up converter with voltage-multiplier modules for sustainable energy
applications, which simultaneously satisfies the requirements for electrical-isolation and safety
regulations, is shown in Fig.
The advantages of the proposed converter are as follows.
• Voltage-multiplier modules make the voltage gain higher and voltage stresses lower.
• The proposed converter possesses continuous and smooth input current, which decreases the
conduction losses, lengthens the life time of the input source, and constrains conducted EMI
problems.
• Due to the passive lossless clamped performance, the leakage energy is recycled. Hence, the
potential for a large voltage spike across the main switch is alleviated and the efficiency is
improved
