A high efficiency PWM buck DC/DC converter high-level model and verification
Based on Simulink tool, the high-level model of 2.0A/375 kHz current controlling PWM buck converter is presented adopting state vector averaging method. The high-level model is verified using Beiling 2¿m/20V bipolar process and 30V/5.0A P-ch power MOSFET. The measured results show that the typical conversion efficiency can be over 90%, the maximum ripple value of output voltage is 32.8 mV, the output voltage error can be in the range of ±3%, the maximum output voltage load regulation is less than 0.3% and the PWM frequency falls to 11.01 kHz during the output circuits being shorted. The current controlling PWM buck DC/DC converter high-level model has been verified by the good performance of the 2.0A/375 kHz buck DC/DC converter.
