STEVAL-ISA019V2、基于 L6565 和 ESBT STC04IE170HV 的使用寬范圍輸入電壓的三相 80W SMPS 演示板

使用 STMicroelectronics 的 L6565 的參考設計

設計簡介

STEVAL-ISA019V2，演示板，用于解釋用于電機驅動和焊接應用的 80W 三相輔助電源的設計。為了在效率和成本方面達到高水平的系統，選擇了L6565 PWM控制器以及STC04IE170HV作為主開關。這些部件的組合為高直流輸入電壓提供了高效的解決方案，這是任何三相應用的典型要求。 L6565 驅動器是一款變頻 PWM 驅動器，適用于在準諧振模式下工作的反激式轉換器設計。它還包括一些非常有用的附加功能。所有的設計選擇都經過徹底的討論，以允許用戶使項目適應特定的需求。輸入電壓還可擴展至 1000 VDC，因為存在足夠的余量

說明

STEVAL-ISA019V2, Demonstration Board used to explain the design of an 80W 3-phase auxiliary power supply for motor drives and welding applications. To reach a high level system in terms of both efficiency and cost, the L6565 PWM controller has been selected as well as the STC04IE170HV as the main switch. The combination of these parts provides a highly efficient solution for high DC input voltage, a typical requirement of any three-phase application. The L6565 driver is a variable frequency PWM driver suitable for a design flyback converter working in quasi-resonant mode. It also includes some very useful additional features. All the design choices are thoroughly discussed to allow the user to adapt the project to specific needs. The input voltage can also be extended up to 1000 VDC as enough margin exists to do so
