Quantization and Sampling Effects in Fast Digitally Controlled Switch-Mode DC/DC Buck Converters
2021 IEEE Industrial Electronics and Applications Conference (IEACon)(2021)
摘要
Software-defined control of DC/DC switch mode power converters features unequaled flexibility compared to analog control. For fast switching converters as recently used for low power applications, digital control may cause steady-state oscillations known as limit cycles. This effect based on a quantized duty cycle is compared to other aberrations such as output ripple voltage, which is inherent to...
