PRD 1378、ADP1048 无桥 PFC 评估套件

使用 Analog Devices 的 ADP1047 的参考设计

设计简介

PRD 1378、ADP1048 无桥 PFC 评估套件。该评估板在典型的交流/直流开关电源中采用无桥升压功率因数校正 (PFC) 拓扑中的 ADP1048。该电路设计用于通过 90 VRMS 至 265 VRMS AC 的交流输入电压源提供 385V/300W 的额定负载。 ADP1048 提供有源 PFC 电路所需的所有功能以及精确的交流功率计量。它实现了接近统一的功率因数、输入电流的低失真、输出电压调节、过流保护、交流线路故障检测和保护、过温保护和电源关断

说明

PRD 1378, ADP1048 Bridgeless PFC Evaluation Kit. The Evaluation board uses ADP1048 in a typical AC/DC switching power supply in a bridgeless boost power factor correction (PFC) topology. The circuit is designed to provide a rated load of 385V/300W from an AC input voltage source of 90 VRMS to 265 VRMS AC. The ADP1048 provides functions all the functions necessary for active PFC circuit plus accurate AC power metering. It achieves near-unity power factor, low distortion of the input current, the output voltage regulation, over current protection, AC line fault detection and protection, over temperature protection and power supply shut-down
