| Abstract: | According to the principle of Buck converter,a small signal mathematical model was established with the principle of state average law and Euler's formula.The dynamic response of Buck converter was analyzed by the model,and the relationship between time of the dynamic response and device was discussed.The compensation correction network was designed according to the small signal model to improve the dynamic response.The excellent dynamic and static performance verifies the accuracy of the mathematical model... |
