解决方案说明

2kW交错PFC解决方案采用经济高效的封装(可根据特定性能标准轻松进行配置),兼具模拟逐周期电流调节的性能和数字控制的灵活性,可以产生功率因数非常高且谐波失真非常低的正弦电源。

数字电源控制基于STNRGPF12数字PFC控制器,该器件与TN3050H-12WY晶闸管和STBR3012整流二极管结合,以固定频率工作在CCM,具有数字浪涌电流限制功能,可以使用固定信号(模拟和数字)平均电流模式控制驱动两个交错PFC通道。该控制器非常适用于600瓦以上的交错CCM升压PFC应用。

The STGW20H65FB IGBTs used for the boost switches are cost effective devices especially designed to minimize losses in power converters thanks to their low VCE (sat) and reduced tail current profile.

To minimize the power losses associated with PFC operation in CCM at high frequencies, the solution includes the STPSC12065 650 V power Schottky silicon carbide diode fast recovery with negligible reverse recovery charge (Qrr) and minimal capacitive turn-off behaviour independent of temperature.

  • 主要产品优势

    STNRGPF12 - 大功率浪涌电流控制器

    STNRGPF12是专为交错PFC升压拓扑设计的数字控制器,适用于大功率应用。它采用基于可控硅整流器的固态解决方案实现数字浪涌电流控制。该控制器能够驱动2个交错通道。该器件以固定频率工作在CCM,并带平均电流模式控制,适用于基于混合信号(模拟/数字)架构的应用。

    STBR3012 - High voltage rectifier

    Thanks to its ultra-low conduction losses, the STBR3012 high voltage rectifier is especially suitable for use as input bridge diode in battery chargers

    STGW20H65FB - Highly efficient IGBT

    These IGBTs is part of the new HB series of IGBTs, which represent an optimum compromise between conduction and switching losses to maximize the efficiency of any frequency converter. Furthermore, a slightly positive VCE(sat) temperature coefficient and very tight parameter distribution result in safer paralleling operation.

     

    STPSC12065 - High performance SiC diode

    Especially suited for use in PFC applications, this ST SiC diode will boost performance in hard switching conditions. Its high forward surge capability ensures good robustness during transient phases.
