基于三电平技术并结合脉冲变压器设计了一个脉冲变换器，并将其用于非热处理灭菌过程。
An impulse converter based on the three-level technology was discussed, which used the up to date power electronic technology and the traditional impulse transformer technology.
但是有一个标示却让我颇为迷惑，于是我叫过销售商，问道：“‘混合脉冲D/A变换器’是什么意思？”
One designation had me puzzled, though, so I called over a salesperson and asked, "What does 'hybrid pulse D/A converter' mean?"
单片机是根据图像处理部分送来的雾滴等级给pwm变换器送不同占空比脉冲来实现对喷头电机进行调速的。
The single chip adjust the speed of sprayer though send the pulse to PWM depend on fogdrop grade sended by image processing system.
