Description: 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。
