高频电源在线切割加工中的作用,早已为人们所重视。本文介绍一种功率较大,调谐灵活,制造使用和维修都很方便的高频电源,它具有如下的几个特点。 1.只用一只三百瓦大功率三极管做功放输出,不需要配对和调整均衡电阻,避免了用多只功率管并联输出的麻烦。 2.主振级用HTL高抗干扰集成电路与非门组成。其频率和脉宽无级连续可调,脉宽比
The role of high-frequency power on-line cutting, has long been valued by people. This article describes a power, tuning flexibility, manufacturing and maintenance are very convenient high-frequency power supply, which has the following characteristics. 1. Only a three hundred watts high power transistor amplifier output, do not need to pair and adjust the balance resistor, to avoid the use of more power tube parallel output trouble. 2. The main vibration level with HTL high anti-interference IC and non-gate components. Its frequency and pulse width continuously adjustable, pulse width ratio
