The purpose of this paper is to present a digital control method which suppresses the delay-time for the switching power supplies. The operation part of power supply has two controllers as the fast PD and the conventional PID, which are processed in parallel. Therefore, the fast PD control can improve the transient response of switching pulses. Obtained simulation results show that the proposed method...
The purpose of this paper is to present a digital control method which suppresses the delay-time for the switching power supply. Generally, there is the delay-time caused by the A/D conversion time and the calculation time in the digital control. It causes the worsening of the transient response and brings the instability of the system. The proposed method can suppress the delay-time and improve the...
