21 Limit cycle based autotuning typical limit cycle oscillation Limit cycle oscillations are caused by non-linear quantization effects in ACD and DPWM. When the resolution of the DPWM is low (compared to ADC)the quantized output cannot result in zero error Digital control of Power Converters 21
22 Limit cycle based autotuning typical limit cycle oscillation Not desirable in steady-state Contain valuable information Characterized by A max, A min, T LC In a digitally controlled power supply they depend on the inductance, capacitance and load (they depend on the digital controller and the input voltage) Only three parameters can be determined In this case only the T LC and the peak to peak amplitude will be used to calculate the C0 and the load frequency amplitude Digital control of Power Converters 22
23 Limit cycle based autotuning Auto-tuner block diagram Not desirable in steady-state Contain valuable information Characterized by A max, A min, T LC In a digitally controlled power supply they depend on the inductance, capacitance and load (they depend on the digital controller and the input voltage) Only three parameters can be determined In this case only the T LC and the peak to peak amplitude will be used to calculate the C0 and the load Digital control of Power Converters 23
24 Limit cycle based autotuning When LCO is steadily excited the total loop has a gain of 1 and a phase shift of 180 degrees N DPWM (A LC, ε) describes the gain of the DPWM to obtain the gain of the DPWM we use describing functions [53] [53] H. Peng, D. Maksimovi c, A. Prodi c, and E. Alarcon, Modeling of quantization effects in digitally controlled DC- DC converters, in Proc.
