| 摘 要： | 传统二次型Boost变换器具有较高的升压能力,但其开关器件的电压、电流应力较大,增加了电路的体积与成本。笔者在传统二次型Boost变换器的基础上,结合高增益Boost三端网络,提出改进二次型Boost变换器,并对其连续工作模式下的工作原理及各开关器件的电压、电流应力进行了分析。分析结果表明,改进二次型Boost变换器不仅升压能力有所提升,而且在输出电压相同的情况下,开关器件的电压、电流应力有所降低。最后,通过仿真分析验证了该变换器的正确性和可行性。

| Abstract: | The traditional quadratic boost converter has the high step-up ability, but it needs high voltage and large current stress, which increases the volume and the cost. Based on the traditional boost converter and a high step-up three-terminal network, an improved quadratic boost converter was presented. The converter''s operation principle and its voltage and current stress of each switch were analyzed when it worked in continuous conduction mode(CCM). The result shows that the presented converter has not only higher step-up ability, but lower voltage and current stress in the case of same output voltage. At last, simulation proved the converter''s correctness and feasibility. |
