The TPI SB-PWM helper block allows the configuration of the TPI PWM outputs to be used with a custom modulator implemented in FPGA. Since the topology of the converter is fixed, the channel assignment and part of the modulators&#8217; configuration are known beforehand.<\/p>\n\n\n\n<p>The topology of the converter and the connection of the PWM channels are shown below. To prevent short-circuiting the DC bus, the upper and lower leg switches always use pseudo-complementary signals with a fixed dead-time of 124 ns. This value was chosen as low as possible to minimize the distortion introduced by the dead-time.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"539\" src=\"https:\/\/imperix.com\/doc\/wp-content\/uploads\/2023\/08\/topology-tpi8032.png\" alt=\"Topology of the TPI8032\" class=\"wp-image-15781\" srcset=\"https:\/\/imperix.com\/doc\/wp-content\/uploads\/2023\/08\/topology-tpi8032.png 1200w, https:\/\/imperix.com\/doc\/wp-content\/uploads\/2023\/08\/topology-tpi8032-300x135.png 300w, https:\/\/imperix.com\/doc\/wp-content\/uploads\/2023\/08\/topology-tpi8032-1024x460.png 1024w, https:\/\/imperix.com\/doc\/wp-content\/uploads\/2023\/08\/topology-tpi8032-768x345.png 768w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption>Topology of the TPI8032<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-table is-style-regular\"><table><tbody><tr><td><strong>PWM channel<\/strong><\/td><td><strong>PWM lane<\/strong><\/td><td><strong>Description<\/strong><\/td><\/tr><tr><td>A<\/td><td>0<\/td><td>PWM High &#8211; Phase A (M0)<\/td><\/tr><tr><td><\/td><td>1<\/td><td>PWM Low &#8211; Phase A (M0)<\/td><\/tr><tr><td>B<\/td><td>2<\/td><td>PWM High &#8211; Phase B (M1)<\/td><\/tr><tr><td><\/td><td>3<\/td><td>PWM Low &#8211; Phase B (M1)<\/td><\/tr><tr><td>C<\/td><td>4<\/td><td>PWM High &#8211; Phase C (M2)<\/td><\/tr><tr><td><\/td><td>5<\/td><td>PWM Low &#8211; Phase C (M2)<\/td><\/tr><\/tbody><\/table><figcaption>PWM channels and lanes assignment<\/figcaption><\/figure>\n\n\n\n<div class=\"wp-block-simple-alerts-for-gutenberg-alert-boxes sab-alert sab-alert-info\" role=\"alert\">The TPI SV-PWM helper block is available starting from <a href=\"https:\/\/imperix.com\/downloads\/\">version 2024.2<\/a> of the SDK.
