摘　　要： 根据电子废弃物等离子体热裂解工艺的高压、大功率及长负载持续率特点，研制了一种高可靠、模块式结构的全数字化大功率等离子体裂解加热逆变电源样机。该电源采用移相零电压零电流开关（ZVZCS）高频软开关逆变技术实现了功率模块的电能高效变换；基于信号磁隔离调制原理设计了功能完善的强功率驱动器，解决了功率器件的可靠驱动和保护问题；利用片上系统（SOC）级ARM嵌入式微处理器搭建全数字化的智能控制器，实现了功率模块的数字化，构建了具备自限流能力的智能功率变换模块；通过控制器局域网络（CAN）实现了各智能功率模块的分层控制和实时协同工作。该样机已在自行研制的电子废弃物资源化裂解实验平台上进行了性能测试，测试结果表明这种电源能满足持续高效裂解生产的需要。 A novel full digital prototype heating inverter with the high reliability and modular structure for plasma based thermal pyrolysis of e-waste was developed. The phase shifting zero voltage zero current switching （ZVZCS） tech- nology was adopted to realize the high efficiency power conversition; An integrated high power driver was designed based on the magnetic isolation modulation principle to ensure the reliable drive and protection for the high power IGBT module; The SOC grade ARM microprocessor was used as the cybernetics core of the full digital intelligent controller, and the intelligent power electronic building block was establised; Through CAN, the hierarchical con- trol and cooperative operation among the intelligent power modules and the system controller were realized. The per- formance test of the heating inverter was carried out on the self-developed plasma based thermal pyrolysis system, and the results indicate that it can fullfil the demand of e-waste thermal pyrolysis.
