DESCRIPTION The DCP0105 family is a series of high efficiency, 5V input Isolated DC/DC converters. In addition to 1W nominal galvanically Isolated output power capability, the range of DC/DCs are also fully synchronizable. The devices feature thermal shutdown, and overload protection is implemented via watchdog circuitry. Advanced power-on reset techniques give superior reset performance and the devices will start into any capacitive load up to full power output. The DCP0105 family is implemented in standard- molded IC packaging, giving outlines suitable for high volume assembly.

隔离升压DC-DC变换器在电动汽车、储能系统、可再生能源发电以及超导储能系统等领域有广阔的应用前景。本文以隔离升压全桥变换器(Isolated Boost Full Bridge Converter,简称IBFBC)为研究对象，针对隔离升压型变换器的拓扑结构、起动问题、隔离变压器漏感问题、软开关问题和输入电感磁复位问题等进行了系统深入的研究，解决了这一类拓扑所共有技术问题。 提出了隔离升压DC-DC变换器拓扑族，分析比较了各种拓扑的特点，确定了以IBFBC为研究对象。对IBFBC进行了详细的稳态分析和小信号建模分析，为其分析、设计和搭建实验平台提供了电路理论基础。 理论上分析了IBFBC起动时存在电流冲击的原因。提出了二种数字化软起动方案，该方案对主电路进行了改造，利用DSP能灵活产生PWM波的特点采用了新的控制策略，成功实现了该系统的软起动。 理论上分析了IBFBC隔离变压器漏感引起功率开关管关断电压尖峰的原因，采用了有源箝位的方法，有效的解决电压尖峰问题。提出了带有源箝位IBFBC的九种PWM控制策略，提出了一种控制型软PWM方法，在不增加主电路元器件的基础上，通过控制PWM的发生方法，实现了有源箝位功率开关管和桥臂功率开关管的零电压开通。 从理论上分析了IBFBC输入电感磁复位问题。在正常停机时提出了一种数字化软停止的方法，控制变换器由Boost工作状态逐渐过渡到Buck工作状态，让输入电感存储的能量逐渐释放掉，最后停止工作。对于故障保护停机，采用了绕组磁复位的方法，把输入电感设计成反激式变换器形式，突然停机时，电感中存储的能量通过反激式绕组释放到输出端，这样保护了变换器不会损坏。 给出了主电路关键器件参数的设计方法，设计了以DSP-TMS320F2407为核心的数字控制单元，编写了DSP控制程序和CPLD逻辑处理程序。研制了一台输出功率5KW，输入电压直流24V，输出电压直流300V的IBFBC,通过全面的性能实验验证了理论分析和仿真结果。 本文立足于IBFBC的关键技术要求，并充分考虑工程应用中的实际因素，进行了理论分析和实验研究，为实际系统方案设计提供理论依据，并已经在实际应用中得到验证。

While simplicity and high effi ciency (for cool running) areno longer optional features in Isolated power supplies, itis traditionally diffi cult to achieve both. Achieving higheffi ciency often requires the use of advanced topologiesand home-brewed secondary synchronous rectifi cationschemes once reserved only for higher power applications.This only adds to the parts count and to the designcomplexity associated with the reference and optocouplercircuits typically used to maintain isolation. Fortunately, abreakthrough IC makes it possible to achieve both high efficiency and simplicity in a synchronous fl yback topology.The LT®3825 simplifi es and improves the performance oflow voltage, high current fl yback supplies by providingprecise synchronous rectifi er timing and eliminating theneed for optocoupler feedback while maintaining excellentregulation and superior loop response.
