中频感应加热以其加热效率高、速度快，可控性好及易于实现机械化、自动化等优点，已在熔炼、铸造、弯管、热锻、焊接和表面热处理等行业得到广泛的应用。
本设计根据设计任务进行了方案设计，设计了相应的硬件电路，研制了20KW中频感应加热电源。
本设计中感应加热电源采用IGBT作为开关器件，可工作在10 Hz～10 kHz频段。它由整流器、滤波器、和逆变器组成。整流器采用不可控三相全桥式整流电路。滤波器采用两个电解电容和一个电感组成Ⅱ型滤波器滤波和无源功率因数校正。逆变器主要由PWM控制器SG3525A控制四个IGBT的开通和关断，实现DC-AC的转换。
设计中采用的芯片主要是PWM控制器SG3525A和光耦合驱动电路HCPL-316J。设计过程中程充分利用了SG3525A的控制性能，具有宽的可调工作频率，死区时间可调，具有输入欠电压锁定功能和双路输出电流。由于HCPL-316J具有快的开关速度（500ns），光隔离，故障状态反馈，可配置自动复位、自动关闭等功能，所以选择其作为IGBT的驱动。
对原理样机的调试结果表明，所完成的设计实现了设计任务规定的基本功能。此外，为了满足不同器件对功率需要的要求，设计了功率可调。这部分超出了设计任务书规定的任务。(induction heating with high heating efficiency, speed and good controllability and easy to mechanization. the advantages of automation, in melting, casting, bending, forging, welding and surface heat treatment and other industries have been widely employed. According to the design tasks for the design of the program design, design corresponding to the hardware circuit, Development of 20 KW induction heating power. The design of induction heating power IGBT used as a switching device, which can work in 10 Hz- 10 kHz frequency band. It consists of rectifier, filter, and the inverter components. Controlled Rectifier not use the entire three-phase bridge rectifier circuit. 2 filter used an electrolytic capacitor and inductor components II-type filter and passive PFC. Inverter mainly by the PW)
