摘　　要：在60kW级燃料电池汽车用DC/DC变换器的开发过程中,需要设计一台虚拟示波器,以满足其多样的测试要求。本文从采样精度、波形分析、波形存储、触发类型以及远程控制等方面对虚拟示波器与传统示波器进行比较,说明了制作虚拟示波器的可行性,并介绍了该示波器的设计过程。在DC/DC变换器的测试工作中,该虚拟示波器达到了预期目标,取得了很好的效果。In the development process of the DC/DC converter in 60kW fuel cell electric vehicle, a virtual oscilloscope is required to satisfy its various testing demand. This paper compares virtual oscilloscope with conventional ones concerning sampling precision, waveform analysis, waveform storage, trigger type and remote control etc, discusses the feasibility of making a virtual oscilloscope and introduces the development process of the virtual oscilloscope. With this virtual oscilloscope, flexible resolution, general usage and expandability are successfully introduced into the automatic testing system for the DC/DC converter in fuel cell electric vehicle. The virtual oscilloscope achieves expectant goals and acquires good effects.
