Abstract
A digital controller comprises two control paths each having an A/D converter. One of the two converters has a substantially higher sampling speed and lower resolution than the other. Thus, one is suitable to deal with the fast responses while the other is suitable to deal with the slow responses, and can replace high-speed high-resolution A/D converter which is high in both cost and power consumption.
Claims19
A digital controller for generating a control signal comprising two control paths each having an analog-to-digital converter and a feedback compensation unit, wherein said two converters are different in sampling speed.
A digital controller for generating a control signal comprising two control paths combined to generate said control signal, each having an analog-to-digital converter and a feedback compensation unit.
A digitally controlled power converter comprising a digital controller for generating a control signal, wherein said digital controller comprises a first control path having a first analog-to-digital converter and a second control path having a second analog-to-digital converter, wherein said first converter has a higher sampling speed than said second converter.
