低压直流供电电路中高压直流的产生

High Voltage Direct-current in Low-voltage Directcurrent

在由低压直流电源供电的电路中,往往电路的某些部位需要使用高于电源所供的电压,将电源所供的低压转换为较高的电压,常用的方法有3种:自举升压、电感升压、逆变升压。结合实际应用电路对各种升压方法从器件选择、升压原理、升压结果等诸方面进行分析、探讨,解决了总体供电电压不变时,局部高压产生的关键性问题。它对电子电器电路的设计人员有一定的启发作用,对优化电路、遴选器件有较强的参考价值。

Because of some circuit node need higher voltage what supplied in the low voltage direct- current circuit, so the source power voltage should be transformed into a higher voltage. There are three general methods, such as bootstrap - boost - voltage, inductance - boost - voltage and inverter - boost - voltage. From choicing components to boost - voltage principle and outcome which are carried on particularly analysised in the paper,and it provids a key to the important problem, what to prod- uct higher voltage inlow voltage direct -current. this would be give some inspiration to electric circuit designer,although it can beneficial to optimizing circuit or choicing components.
