本文导读:B+、B+1、B+2的定义为何增设 B+2电源及 B+2电源的两项基本要求B+2升/降压供电电源的实质直流稳压型 B+2电源的蔽端B+2脉冲供电的基本原理及优势脉冲供电 B+2电源的实例为了避免造成概念上的混淆,本文中对 B+、B+1、B+2的含义加以规范。B+为多年来对行扫描输出级供电的俗称。B+1、B+2的提法,是为区分变频电视机、自动扫描显示器中行输出级供电电源两个不同电路部分的输出电压。比如:视频设备中主开关电源输出的 B+电压,并不直接向行输出级供电,而是经升/降压变换后提供行供电则称为 B+1。而升/降压降稳变换后输
This article reads: B +, B +1, B +2 definition of why the addition of B +2 power supply and B +2 power supply two basic requirements B +2 liter / step-down power supply DC DC B +2 power supply Basic principles and advantages of pulse-side B + 2 pulse power supply Examples of pulse-fed B + 2 power supply In order to avoid conceptual confusion, the meaning of B +, B + 1 and B + 2 is regulated in this paper. B + is the common name for powering line scan output stages over the years. B + 1, B + 2 is the reference to distinguish the variable frequency TV, automatic scan display output power supply line level two different circuit part of the output voltage. For example: video equipment, the main switching power supply B + voltage output, not directly to the line output stage power supply, but by the step-down conversion provides line power supply is called B +1. The rise / fall steady buck change lose
