 随着电动汽车的发展，车载音响系统的信道的数量和输出功率均在逐步上升。D类功放以小尺寸，高输出功率和高效率的优点，成为车载音频类产品的中坚力量。D类功放将输入的声音信号同三角波进行比较，生成PWM波形，并通过LC滤波器将声音还原，实现声音放大。为实现更好的音频表现及满足车载EMI需求，合理的LC滤波器设计和选型变得尤为重要。文主要针对D类功放LC滤波器电感电容值进行推导计算</description><dc:language>zh-CN</dc:language><generator>Telligent Community 13</generator><item><title>回复:D类功放LC 滤波器数值计算及选型指导</title><link>https://e2echina.ti.com/blogs_/b/behindthewheel/posts/d-lc</link><pubDate>Sat, 04 Jul 2026 09:55:17 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:d7cb3ba1-1f61-4b4e-8576-3d2b12df7a65</guid><dc:creator>user4781018</dc:creator><slash:comments>0</slash:comments><description>&lt;p&gt;&lt;img src="/resized-image/__size/640x480/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-d7cb3ba1-1f61-4b4e-8576-3d2b12df7a65/pastedimage1783158893335v1.png" alt=" " /&gt;这个Q值计算，代入的结果为1.1009，与实际的结果不同，是什么原因&lt;/p&gt;&lt;img src="https://e2echina.ti.com/aggbug?PostID=53625&amp;AppID=78&amp;AppType=Weblog&amp;ContentType=0" width="1" height="1"&gt;</description></item></channel></rss>
