These trap air, and air is a poor thermal conductor. Thermal paste fills those gaps, improving heat transfer efficiency by reducing <a href=\"https:\/\/haktak.com\/de\/what-is-thermal-resistance\/\">W\u00e4rmewiderstand<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In inverter systems, this matters because:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>IGBTs and MOSFETs generate significant heat during switching<\/li>\n\n\n\n<li>Heat density is high and localized<\/li>\n\n\n\n<li>Poor heat transfer leads to rapid temperature rise<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Typical inverter losses can reach <strong>75\u2013125W in a 5kW system<\/strong>, meaning continuous heat must be efficiently dissipated.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Thermal Paste Selection Matters More in Inverters<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Thermal paste selection for CPUs is forgiving.
