  • UC1875: UC1875输出脉冲一闪一闪

    Part Number: UC1875 Tool/software: UC1875在开环时,输入条件:19脚三角波峰值4.1V,频率40KHz,2脚4.8V。结果其输出脉冲波形,一闪一闪的,间隔1秒左右,即1秒有1秒无。不知道是哪里的问题,是板子布的有问题还是别的原因? 拿正常的板子做对比,正常板子就是持续的输出。

  • UC1875: UC1875的移相角究竟能不能控制输出电压?

    Part Number: UC1875 Tool/software: 测试UC1875时,发现输出采样回4脚的各种电压,只要比3脚电压高的话,误差放大器输出恒定高电平,移相角也是恒定的。此时似乎输出电压是不受移相角所控制的(常规的是通过移相角去控制输出电压的)。 貌似只有平衡时,才构成整个回路的闭环。 那么,怎么通过移相角去控制输出电压呢?即移相角大点输出就大点,移相角小点输出就小点
