准谐振式开关电源的设计      摘要      随着电力电子技术的发展，电力电子设备与人们的工作、生活的关系日益密切，而电子设备都离不开可靠的电源。开关电源产品广泛应用于工业自动化控制、特殊用途设备、仪器仪表、半导体制冷制热等领域。
目前，开关电源以小型、轻量和高效率的特点被广泛应用于电子设备，是当今电子信息产业不可缺少的一种电源方式。目前由于开关电源频率的提高，需要减少开关损耗。谐振电路，以使开关上的电压或通过开关的电流呈正弦波，在减少开关损耗的同时也可控制浪涌的发生，这种方式的开关电源称为谐振式开关电源。      准谐振开关电源使开关电源的可靠性、纹波干扰等问题得到很大改善，材料成本不增加而体积、重量却可以大大减少。除此之外，谐振式开关电源电路还可以克服PWM   方式对负载的瞬态响应较差和易辐射等缺点，利用高频驱动的作用，降低损耗，提高效率，减少噪声。
其中，部分谐振方式，将会成为主流技术。部分谐振转换电路技术，在理论上即可实现高频化又可降低噪声，但部分谐振转换技术的实际应用仍存在着技术问题，故仍需在这一领域开展大量的工作，以使得该项技术得以实用化。      本文叙述了准谐振式开关电源的设计过程，描述了主电路的参数计算、器件的选择，介绍了NCP1207芯片实现准谐振控制的电路完整形式，实现了退磁检测、过流保护、过压保护、电压反馈。
希望我的回答可以帮助您。
