class=\"wp-block-paragraph\">For a controlled rectifier, the DC bus and load can influence device voltage during commutation. For an AC controller, the load&#8217;s inductive behavior and switching sequence can matter. Avoid broad assumptions based only on load power. Preserve the actual schematic and waveform analysis as the source of the stress figure used in selection.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\u8003\u91cf\u555f\u52d5\u8207\u6545\u969c\u72c0\u614b<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\u82e5\u50c5\u4f9d\u64da\u7a69\u614b\u5c0e\u901a\u72c0\u614b\u9032\u884c\u7be9\u9078\uff0c\u53ef\u80fd\u6703\u5ffd\u7565\u958b\u6a5f\u3001\u95dc\u6a5f\u3001\u9598\u6975\u9a45\u52d5\u640d\u5931\u3001\u76f8\u4f4d\u640d\u5931\u6216\u6545\u969c\u97ff\u61c9\u671f\u9593\u7684\u963b\u65b7\u72c0\u614b\u3002\u9700\u91d0\u6e05\u4e0a\u8ff0\u60c5\u6cc1\u4e2d\u54ea\u4e9b\u5177\u6709\u53ef\u4fe1\u5ea6\uff0c\u4ee5\u53ca\u5b83\u5011\u6703\u6301\u7e8c\u591a\u4e45\u3002\u8ca0\u8cac\u7684\u5de5\u7a0b\u5e2b\u61c9\u6c7a\u5b9a\u54ea\u4e9b\u5c6c\u65bc\u91cd\u8907\u6027\u7684\u8a2d\u8a08\u60c5\u6cc1\uff0c\u54ea\u4e9b\u5c6c\u65bc\u4f8b\u5916\u4e8b\u4ef6\u3002\u6b64\u5206\u985e\u5c07\u6c7a\u5b9a\u61c9\u9069\u7528\u54ea\u9805\u8cc7\u6599\u8868\u8072\u660e\u3002.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u5728\u672a\u6aa2\u67e5\u6ce2\u5f62\u53ca\u88fd\u9020\u5546\u898f\u5b9a\u689d\u4ef6\u4e4b\u524d\uff0c\u8acb\u52ff\u5c07\u7570\u5e38\u4e8b\u4ef6\u6b78\u985e\u70ba\u91cd\u8907\u6027\u8a55\u7d1a\u3002\u53cd\u4e4b\uff0c\u4ea6\u8acb\u52ff\u4f9d\u8cf4\u975e\u91cd\u8907\u6027\u7a81\u6ce2\u503c\u4f86\u627f\u53d7\u6b63\u5e38\u904b\u4f5c\u671f\u9593\u767c\u751f\u7684\u4e8b\u4ef6\u3002\u4f9b\u61c9\u5546\u61c9\u5145\u5206\u7406\u89e3\u4e8b\u4ef6\u7684\u63cf\u8ff0\uff0c\u800c\u975e\u50c5\u7372\u77e5\u672a\u6a19\u660e\u767c\u751f\u983b\u7387\u8207\u6301\u7e8c\u6642\u9593\u7684\u6700\u5927\u6578\u503c\u3002.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\u8907\u7fd2\u96fb\u58d3\u4e0a\u5347\u8207\u63db\u5411<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Dynamic voltage stress can be important for thyristors. A fast voltage rise across a blocking device and the conditions during commutation may have limits separate from static peak voltage. Ask the engineering team to evaluate these using the exact device&#8217;s application data.
