| Abstract |
This paper proposes instantaneous following control method to control pulse modulation switching converter by using the principle that reset time of integrator is inverse proportion in size of integrator input voltage. Proposed control method acts of fixed frequency and control switch calculates time of become turn on and turn off using analog integrator. Duty ratio that express switching time of converter is depended on mean value of switching variable and following time consists in one cycle. Follow to do order exactly stationary state as well as transition state, and controller corrects mean value of control variable and control reference value and control as control error gets into zero. Proposed control method could experimented and know that experiment result and theory are agreeing well through this using the buck converter. |
