集成耦合电感与开关电容的交错式高升压变换器

A new interleaved high step-up dc-dc converter is proposed for distributed generation systems. By integrating coupled-inductor and switched-capacitor techniques, the proposed converter achieves a very high step-up voltage gain without an extreme duty cycle or a high turns ratio. Also, a very low switch voltage stress can be achieved; thus, low-voltage-rating mosfets with a small on-resistance can ...
