Digital Control of DC-DC Converter Using Low Cost Processor

In SMPS, digital control techniques are adopted widely. But Digital controlled SMPS has poor performance of regulation and transient response than analog controlled SMPS. Delay time of control computing and low frequency of updating duty ratio make digital controlled SMPS poor performance. This paper proposed the optimized control computation to increase not only frequency of updating duty ratio but also switching frequency of SMPS.
