| Abstract |
This paper presents a novel adaptive-hysteresis predetermined constant frequency current-mode
control for PWM DC/DC power converters. Theoretical examination is performed and one simple and
easy-to-apply control low is derived. It is concluded that very fast and accurate response is maintained,
while predetermined constant frequency steady-state operation is achieved. Moreover, the control low
attains very small frequency variations during transients. Experimental 2KW buck converter is built to
verify the theory. Some steady-state and transient tests are performed with results, which are
consistent with the theory. |
