AC-DC 辅助电源
英飞凌提供多样且可扩展的产品组合,助力用户设计和制造高效、紧凑的 AC-DC 辅助电源
-
在这个页面上
概述
借助英飞凌的辅助电源解决方案,提升系统稳定性。我们可扩展的 CoolSET™ 产品系列可为家用电器、服务器、数据中心以及工业和消费应用等关键系统提供主电源或备用电源。高性能 CoolSET™ 可实现最大稳定性和效率,支持隔离式和非隔离式电源,功率高达 100W。
产品优势
- 高效率
- 集成SR控制器
- 低元件计数
- 支持宽输入电压
- 支持反激式和降压式电路
- 支持 ZVS、FF和QR工作

关于
许多电器和设备都需要一个额外的 SMPS 电源,它能够独立于主电源运行,支持待机模式。这些辅助电源有隔离和非隔离之分,功率从几瓦到几十瓦不一。为确保性能,工程师须根据效率、尺寸、安规和成本的需求,选择合适的电源拓扑,如反激或准谐振。
英飞凌的 CoolSET™ AC-DC 集成功率级具有更高的可靠性和更出色的性能,可为辅助电源提供额外的保护,以提高辅助电源的系统稳健性。第五代控制器整合了高压电源集成电路和内部 AC-DC 开关稳压器,在确保安全的基础之上实现了快速启动。
完整的 AC-DC 集成功率级(IPS)产品组合包括固定频率(FF)CoolSET™ 和准谐振(QR)CoolSET™ 系列产品。CoolSET™ 集成了 700 V、800 V 和 950 V 雪崩式坚固 CoolMOS™ P7 系列,采用通孔和 SMD 两种封装,无需散热片,尺寸更小,从而降低了 BOM 成本。准谐振式 CoolSET™ 采用第二代和第五代配置,而固定频率 CoolSET™ 产品系列采用第三代和第五代配置。
您可通过英飞凌的开关电源设计工程师和 PowerEsim 设计软件按需创建定制的电源电路,并参照我们的评估板产品组合或全新的设计得到您要的解决方案。该环境提供电源仿真和优化功能,可为您节省开关电源设计过程各个阶段的时间。
模拟、优化、导出。您可用以下方式完成设计:运行电气仿真、导出到您最常用的 CAD 工具、打印设计出的 PDF 报告或开始新设计。选择权在您的手里。
您可以在下面的设计支持部分亲身体验一下。
英飞凌提供许多设计支持工具,为您的设计工作提供指导和帮助。我们要特别强调的两点是:
DEMO_5GR2280AG_22W1 是一款 22 W 演示板,可在宽输入范围下运行,专为离线 SMPS 应用而开发。它使用了一种新型的 PWM 固定频率 CoolSET™,型号为 ICE5GR2280AG,采用 DSO-12 封装,内置了 800 V 的 MOSFET。它的优势在于效率高,可在负载较轻时降低工作频率,同时还能够通过可调节的输入过压保护,保证运行的稳定性。它最适合用于空调、冰箱、服务器、电脑电源和音频中的辅助电源设计。
此外,DEMO_5QR0680BG_42W1 使用新型 ICE5QR0680BG PWM 准谐振反激式 CoolSET™,采用 DSO-12 封装,并集成了 800 V 的 MOSFET。它利用准谐振开关实现了高效率,同时还是一种经济实惠的方案,可提供强大的线电压故障保护。该评估板适用于宽压输入范围,专为离线式 SMPS 应用而设计。
