保护可编程直流电源: 防止电感、电容和振荡负载的不利影响 Tuesday, October 28, 2025
连接直流电源与负载看似简单,但在某些复杂场景下可能充满挑战。尽管电源制造商设计产品时已确保其在多种负载下的稳定性,但某些负载特性仍可能带来风险,甚至损坏电源的输出级。感性负载、容性负载以及负载电流快速变化的负载可能引发振荡,危及电源和负载设备。此外,感性和容性负载会向电源反馈能量。本文将探讨直流电源可能面临的各类危险负载类型,并提供解决方案,以确保电源可靠运行并保护负载安全。 感性负载: 感性负载(如电机、螺线管和机电继电器)可能成为能量源,向电源反馈能量并造成损坏。当电压和电流施加到感性负载时,会建立磁场并储存势能。在电源断开时,磁场崩溃,产生反向极性的电压尖峰。这种反向电动势可能损坏电源的输出级。 为保护电源,可在电源输出端并联一个反向偏置二极管,称为续流二极管或飞轮二极管。当电源关闭时,该二极管为感性负载产生的电流提供通路,从而保护电源免受反向电动势冲击 …
What’s the Best AC Input for Your DC Power Supply? Tuesday, July 30, 2024
An alternating current (AC) input feeds AC power into your direct current (DC) power supply. Choosing the right AC input for your power converter or switching power supply is critical for ensuring adequate performance, efficiency, and reliability. AC input refers to the type of alternative current input power that feeds into the machine. The device then converts the input voltage and input current …
在电路中确定可编程直流电源准确性的因素 Friday, January 19, 2024
测量精度是所有测试系统的基本规格。精度规格是系统中所有设备和系统整体布局的综合考量,包括布线选择和配置。确定测试系统精度必须包括测试系统中所有可编程直流电源的精度。那么,是什么定义可编程直流电源的精度呢?接下来我们将从以下方面介绍影响可编程直流电源精度的设备参数和布线配置。 需要考虑的精度术语  远程感测的重要性 为电源到负载布线的建议 可编程直流电源的精度规格和术语 让我们首先看看设备的其他规格,这将有助于更好的理解电源的输出精度。 显示精度 – 此规格通常是设备精度的主要贡献者。这个参数基本上是电源输出和反馈路径中所有组件的误差预算。显示精度表示为满量程电压的百分比数值或输出电压设置的百分比数值。 负载调节 – 负载调节定义了随着负载电阻的减小,需要更多电流来维持固定电压值时,输出电压的下降 …
Reaping Energy Savings With Regenerative Power Tuesday, August 8, 2023
Programmable DC power supplies have long been instrumental in power electronics and battery testing. These supplies are extensively used for performance testing and product characterizations. However, a common issue arises when dealing with excess energy generated during burn-in tests, battery cycling or discharging energy storage systems before shipment. Traditionally, this surplus energy is …

Considerations for Selecting an Electronic Load Saturday, July 30, 2022
When it comes to testing and development in electronics, selecting the right tools is vital. One of the most important tools you can have in your arsenal is an electronic load. Whether you’re working on power supplies, batteries, resistors, or other electronic components, electronic loads allow you to simulate real-world operating conditions. However, it’s important that you choose the right type …
Repurposing and Recycling EV Batteries Tuesday, July 6, 2021
It’s no secret that there are more electric vehicles (EVs) on the road today than ever. Since 2015, the number of electric vehicles worldwide has grown from 1.4 million to more than 8 million today. Because EVs emit far fewer hydrocarbons than vehicles powered by internal combustion engines, they are an important part of the plan to combat climate change. EVs do, however, present other challenges …
