具有高电压增益和降低电压应力的二次升压DC-DC变换器

This paper proposes a quadratic boost dc-dc converter with a high voltage gain and reduced voltage stresses. The conventional quadratic boost converter has a limited voltage gain, which is not suitable for high-step-up applications with various microgrids. In the proposed converter, to improve the voltage gain beyond that of a quadratic converter, a coupled inductor is adopted. Additionally, passi...
