| 1. | In order to conquer the shortcoming of general pwm forcibly switch technology , it takes advanced soft switch technology to recede the switch spoilage of power component and will be benefit to improve the frequency of switch electroplating power and raise the control precision and smooth of the output voltage and current of the electroplating power . it designs a digital software electroplating power that bases on the 80c196mc and epld ( erasable programmable logic device )
为了克服常规pwm硬开关控制技术的缺陷,本文采用先进的软开关技术,大大降低了功率开关器件的开关损耗,提高了电镀电源的开关频率,改善了输出电源电压和电流的平滑性与控制精度,采用基于80c196mc单片机与可擦除可编程逻辑器件epld组成的全数字化控制系统,研制了一台软开关电镀电源。 |
