Description
技术领域technical field

技术背景technical background
在电子电路领域中,低压直流电源常常无法满足负载所需的高压,故需要对低压直流电源进行升压。在升压电路中,通常使用的方法就是利用升压变压器进行升压,然后再用二极管整流得到所需要的高压直流电。这种电压变换方法简单实用,但它体积大比较笨重,电能损耗大利用率低,而且变压器本身就有电磁干扰,会对电路产生一定的影响。在使用过程中非常不便,也浪费了大量的能源。In the field of electronic circuits, the low-voltage DC power supply often cannot meet the high voltage required by the load, so it is necessary to boost the voltage of the low-voltage DC power supply. In the step-up circuit, the commonly used method is to use a step-up transformer to boost the voltage, and then rectify it with a diode to obtain the required high-voltage direct current. This voltage conversion method is simple and practical, but it is bulky and cumbersome, the power loss is large and the utilization rate is low, and the transformer itself has electromagnetic interference, which will have a certain impact on the circuit. Very inconvenient in use, also wasted a large amount of energy.
