[原创] ST STNRGPF12两路交错式CCM PFC数字控制器解决方案

ST公司的STNRGPF12是两路交错式CCM PFC数字控制器,嵌入了数字浪涌电流限制器功能,控制器能驱动多达两个交错式通路.器件工作在固定频率CCM,用平均电流模式控制,基于混合信号(模拟/数字)架构.控制器可通过专用的软件工具(eDesignSuite)进行到底配置,以适合各种特殊的应用.该工具产生完整的电路图,包括完全的材料清单和最终二进制目标代码(FW),并下载到集成电路中.STNRGPF12采用连续导通模式,软件起动管理,支持突发模式,具有通路电流平衡功能,可编程切相,冷却系统,PFC故障和PFC OK等状态指示器信令,采用专用图像工具可配置驱动器以及可编程快速的过流和热保护.适用于大于600W的应用如焊接,空调器,工业马达和UPS,充电器和大功率系统.工作温度-40℃到105℃.本文介绍了STNRGPF12主要特性,控制方案图,框图以及STEVAL-IPFC12V1 2 kW 交错式PFC评估板主要特性和框图,以及电源板,控制板与适配板的电路图,材料清单.

The STNRGPF12 digital controller is designed forinterleaved PFC boost topologies and intendedfor use in high power applications.

It features a digital inrush current controlimplemented with a solid state solution based on a silicon controlled rectifier. The controller candrive up to 2 interleaved channels.

The device works in CCM at fixed frequency withaverage current mode control, in applicationsbased on a mixed signal (analog/digital)architecture.

The controller can be configured through adedicated software tool (eDesignSuite) to match awide range of specific applications. The toolgenerates a full schematic including a completelist of material and the final binary object code(FW) to be downloaded to the IC.
