摘要

首次制定了防止电源模块局部放电的系统设计规则，并将其纳入电子设计自动化工具PowerSynth中。该工具支持可靠性约束的现有框架已被利用，以结合由有限元模拟提供的电压和材料特定设计规则。通过这些模拟，确定了一个新的通用公式，可以预测各种电压和封装剂的最小走线间隙。该工具现在可以生成可运行至30kV的电源模块布局。

General Equation to Determine Design Rules for Mitigating Partial Discharge and Electrical Breakdown in Power Module Layouts

Systematic design rules to prevent partial discharge in power modules have been formulated for the first time and incorporated into PowerSynth, an electronic design automation tool. The tool’s existing framework for supporting reliability constraints has been leveraged to incorporate voltage and material specific design rules that are informed by finite element simulations. A new general equation to predict the minimum trace gap for various voltages and encapsulants has been determined from these simulations. The tool can now generate layouts of power modules that can be operated up to 30kV.
