Buck RC Snubber Designer

The Biricha Buck RC Snubber Design Tool is an intuitive online calculator designed to help engineers optimize snubber circuits for Buck converters. By entering parameters such as input voltage, switching frequency, and the ringing frequency at the switch node, the tool calculates the ideal resistor and capacitor values for low-side and high-side switches. Reducing ringing not only minimizes power dissipation but also significantly improves EMC performance by decreasing high-frequency noise emissions. The tool guides users through selecting appropriate components, estimating power dissipation, and iteratively refining their snubber design for optimal efficiency and electromagnetic compatibility. This makes it an essential resource for creating reliable and compliant Buck converter designs.

Flyback RC Snubber Designer

The Biricha Flyback RC Snubber Design Tool is a powerful online calculator that simplifies the design of snubber circuits for Flyback converters. By entering parameters such as the transformer turns ratio, output voltage, and switching frequency, the tool calculates optimal resistor and capacitor values for both the primary and secondary side switches. It also helps identify and mitigate high-frequency ringing, reducing power dissipation and improving the overall EMC performance of your Flyback converter. With clear step-by-step guidance for component selection and iterative refinement, this tool is an useful resource for engineers designing efficient and reliable Flyback power supplies.

Würth Flex Transformer Selection Tool

The Biricha Würth Flex Transformer Selection Tool simplifies the complex process of selecting and configuring transformers for low-power DC/DC applications. By leveraging Würth’s WE-Flex range of pre-built transformers, which feature gapped and ungapped core options, engineers can avoid the challenges of designing custom transformers. The tool, paired with detailed step-by-step guidelines and equations, enables designers to configure the transformer’s windings to achieve the desired turns ratio and inductance while ensuring reliable performance without overheating. With this tool, users can quickly calculate critical parameters such as rated current, saturation current, and inductances, enabling fast and efficient power supply design for Flyback and other topologies.
