| Abstract |
This paper presents a predictive dead-beat
current controller which uses an online estimation of the
system’s behavior. Only the measurement of inductor current
is necessary for the realization. This idea also works
for variable parameters of the load and of the power supply
as well. Here pulse width modulation (PWM) method with
constant frequency is taken into use, to limit switching losses.
After a setpoint step-change, a new switch duty cycle is
computed. If possible, the new setpoint is reached after one
pulse period. That means, after the setpoint step-change,
it takes one pulse period for the calculation and one more
period to reach the final value. |
