IGBT高频逆变电源主控电路的设计
摘要
本文在分析了IGBT(绝缘栅双极晶体管)特性的基础上，设计了一台容量为2KVA、频率为20KHZ的高频逆变电源。给出了直流斩波电路及全桥逆变电路的工作原理，此高频逆变电源可将75～130V的蓄电池直流电压逆变为110V，20KHZ的交流电压。
对高频逆变电源的控制主要分两部分：逆变控制和斩波控制。斩波控制可将75～130V波动的蓄电池直流电压变成70V的直流电压。逆变控制可将此直流电压逆变为70V、20KHZ的交流电压，最后经变压器得到110V、20KHZ的交流电压。驱动电路的设计使得该系统的应用更加方便易行。设计中说明了各元件参数的计算和选择方法，提出了对IGBT的短路保护方案。对设计方案进行了实验，并给出了实验结果和分析。
This paper has designed a inverter power supply of volume 2KVA,working frequency 20KHZ.,based on that has analyzed the characteristic of IGBT (Insulated Gate Bipolar Transistor).It was provided the working theory of DC voltage circuit and bridge type invert circuit. The high frequency inverter power can invert 75-130 volt vibrating DC voltage which come from battery charge into 110 volt,20KHZ AC voltage.
The control of high frequency inverter power consists of two parts:Chopper Control and Inverter Control. Chopper Control can change 75-130 volt vibrating DC voltage into 70 volt DC voltage and Inverter Control can invert the DC voltage into 70 volt,20KHZ AC voltage,at last,from transformer we can get 110 volt,20KHZ AC voltage. The drive circuit is so convenient and easy to use. Every component in the system is designed and chosen. This paper presents the way of shot circuit protection,and gives the experiment,analyses the result.
