This paper investigates an energy-based approach for the prediction of limit-cycle oscillations (LCOs) in digitally controlled dc-dc converters due to quantization effects on the A/D converters and digital pulse-width modulator (DPWM). Existing static and dynamic models predict the existence of only a part of limit cycle oscillations, so that extensive time-domain simulations are usually needed in order to verify the presence of limit-cycle oscillations under different load and input voltage… CONTINUE READING
