低压直流供电电路中高压直流的产生

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。

High Voltage Direct - current in Low - voltage Direct - current

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 product higher voltage in low voltage direct-current.this would be give some inspiration to electric circuit designer,although it can beneficial to optimizing circuit or choicing components.
