This white paper discusses how market trends, the need for increased productivity, and new legislation have accelerated the use of safety systems in industrial machinery. This TÜV-qualified FPGA design methodology is changing the paradigms of safety designs and will greatly reduce development effort, system complexity, and time to market. This allows FPGA users to design their own customized safety controllers and provides a significant competitive advantage over traditional microcontroller or ASIC-based designs. Introduction The basic motivation of deploying functional safety systems is to ensure safe operation as well as safe behavior in cases of failure. Examples of functional safety systems include train brakes, proximity sensors for hazardous areas around machines such as fast-moving robots, and distributed control systems in process automation equipment such as those used in petrochemical plants. The International Electrotechnical Commission’s standard, IEC 61508: “Functional safety of electrical/electronic/programmable electronic safety-related systems,” is understood as the standard for designing safety systems for electrical, electronic, and programmable electronic (E/E/PE) equipment. This standard was developed in the mid-1980s and has been revised several times to cover the technical advances in various industries. In addition, derivative standards have been developed for specific markets and applications that prescribe the particular requirements on functional safety systems in these industry applications. Example applications include process automation (IEC 61511), machine automation (IEC 62061), transportation (railway EN 50128), medical (IEC 62304), automotive (ISO 26262), power generation, distribution, and transportation. 图Figure 1.

为有效控制固态功率调制设备,提高系统的可调性和稳定性,介绍了一种基于现场可编程门阵列( FPGA)和微控制器(MCU) 的多路高压IGBT 驱动触发器的设计方法和实现电路。该触发器可选择内或外触发信号,可遥控或本控,能产生多路频率、宽度和延时独立可调的脉冲信号,信号的输入输出和传输都使用光纤。将该触发器用于高压IGBT(3300 V/ 800 A) 感应叠加脉冲发生器中进行实验测试,给出了实验波形。结果表明,该多路高压IGBT驱动触发器输出脉冲信号达到了较高的调整精度,频宽’脉宽及延时可分别以步进1 Hz、0. 1μs、0. 1μs 进行调整,满足了脉冲发生器的要求,提高了脉冲功率调制系统的性能。
