Abstract

A digital-control sensorless current-mode boost DC-DC converter is presented in this paper. By using the proposed sensorless current-mode control, the requirement for implementation of current sensor for conventional current-mode dc-dc converter is relaxed. Moreover, the converter can seamlessly switch between CCM and DCM operation as in conventional current-mode control. With this method, the non-limited-cycle for digital-control current-mode converter is realized. Lower resolution of DPWM can be used to avoid the appearance of limited cycle, regardless of loading condition.

具有非零误差仓补偿和无缝模式转换的数字控制无传感器电流模式升压转换器

本文提出了一种无传感器的数字控制电流型升压DC-DC变换器。采用本文提出的无传感器电流模式控制，降低了传统电流模式dc-dc变换器对电流传感器的要求。此外，变换器可以在CCM和DCM之间无缝切换，就像传统的电流模式控制一样。利用该方法，实现了数字控制电流型变换器的无限环。低分辨率的DPWM可以避免有限周期的出现，无论负载条件。
