Freescale PXS20三相太阳能逆变器解决方案

Freescale公司的PXS20是32位双核双发射的Power Architecture微控制器,满足安全标准IEC61511和IEC61508 (SIL3),能降低设计复杂性和减少所用元件.PXS20采用高性能的e200z4d双核,核频率高达120MHz,双发射级流水线核,可变长度编码(VLE),集成了存储器管理单元(MMU)和信号处理引擎,带误差检测代码的4KB指令缓存,主要用在消费类电子,工业控制,太阳能逆变器,机器人和马达控制等.本文介绍了PXS20主要特性,方框图,以及采用PXS20控制的太阳能三相逆变器基本架构,1kW, 3kW,10kW和大于10kW以及微逆变器的太阳能三相逆变器解决方案架构图.

The PXS20 family of 32-bit Power Architecture® microcontrollers is designed to specifically address the requirements of the safety standards IEC61511 and IEC61508 (SIL3). It reduces design complexity and component count by putting key functional safety features on a single chip with a dual-core, dual-issue architecture, which can be statically switched between lockstep mode (redundant processing and calculations) to decoupled parallel mode (independent core operation). The PXS20 microcontrollers are SafeAssure solutions.
