EG8011单相SPWM逆变器专用芯片

  EG8011是一款增强型的纯正弦波逆变器控制芯片。应用于 DC-DC-AC 两级功率变换架构或 DC-AC 单级工频变压器升压变换架构，外接 20MHz 晶体振荡器，能实现高精度、失真和谐波都很小的纯正弦波 50Hz 或 60Hz 逆变器专用芯片。该芯片采用 CMOS 工艺，内部集成 SPWM 正弦发生器、死区时间控制电路、幅度因子乘法器、软启动电路、保护电路、串行液晶驱动模块等功能。  在 EG8010 的基础上，取消了双极型调制，增加更加先进的单极性双边调制方式，并完美兼容单极性调制方式的逆变电路。增加了调制频率 10KHz 和 20KHz 配置引脚，应用更加广泛。提升了了 SPWM ·引脚设置 4 种纯正弦波输出频率：\n\t\t\t\t\t50Hz 纯正弦波固定频率\n\t\t\t\t\t60Hz 纯正弦波固定频率\n\t\t\t\t\t0-100Hz 纯正弦波频率可调\n\t\t\t\t\t400Hz 纯正弦波固定频率\n\t\t\t\t\n ·引脚设置 2 种调制频率\n\t\t\t\t\tSPWM 调制频率 20KHz\n\t\t\t\t\tSPWM 调制频率 10KHz\n\t\t\t\t\n ·自带死区控制，引脚设置 4 种死区时间：\n \t\t\t\t300nS 死区时间\n \t\t\t\t500nS 死区时间\n \t\t\t\t1.0uS 死区时间\;
