摘    要:针对数字控制器在实施控制上的缺点,尤其是从调节信号到驱动波形的响应这一环节存在延时的问题,提出了改善措施。在比较几种设计方案的基础上,提出了一种新的频率与占空比联合调节的调节方案。在该方案中,采用频率调节来补偿占空比的调节精度。试验证明,该方案不仅电路元件少,成本低,而且响应快速,调节精度高。

关 键 词:变换器  数字控制  控制器  脉宽调制

Abstract:According to the demerits including the poor adjust precision and the considerable delay between digital adjust and the main switch driving response in high frequency for the digital controller.A method combined period with duty cycle adjust was presented after researched the merits and the disadvantages of three usual digital adjust methods.The proposed method can compensate the low precision of the traditional duty adjust,reduce the drive response delay to zero,reduce the components.The above merits of the proposed method including few components,lower cost,quicker response and higher precision of the proposal method were verified by the experimental result.
Keywords:converter  digital control  controller  PWM
