高性能化主要包括低损耗、高速度和高可靠性这三个方面。预计在21世纪IGBT、智能化功率模块(IPM)等器件的导通电压可降到1V以下，而MOSFET、IBGT、MCT等器件的应用频率将达到兆赫数量级。

智能化的发展是系统智能集成(ASIPM)，即将电源电路、各种保护以及PWM控制电路等都集成在一个芯片上，制成一个完整的功率变换器IC。集成电力电子模块(IPEM)是将控制、驱动、自动保护、自诊断功能的IC与电力电子器件集成在一个模块中。由于不同的元器件、电路、集成电路的封装或相互连接产生的寄生参数已成为决定电力电子系统性能的关键，所以采用IPEM方法可减少设计工作量，便于生产自动化，提高系统质量、可靠性和可维护性，缩短设计周期，降低产品成本。

6．3模块化

模块化有两方面的含义，其一是指功率器件的模块化，其二是指单元的模块化。常见的功率器件模块包括开关器件和与之串并联的续流二极管，实质上都属于“标准”功率模块(SPM)。近年来，有些公司如深圳中电华星把开关器件的驱动保护电路也装到功率模块中构成IPM，不但缩小了整机的体积，而且更加方便了整机的设计与制造。实际上，由于频率不断提高，致使引线寄生电感、寄生电容的影响愈加严重，对器件造成更大的电应力，具体表现为过电压、过电流毛刺。为了提高系统的可靠性，有些制造商开发了“用户专用”功率模块(ASPM)，它把一台整机的几乎所有硬件都以芯片的形式安装到一个模块中，使元器件之间不再有传统的引线连接，这样的模块经过严格、合理的热、电、机械等方面的设计，产品性能优良。
