| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have proposed a control method of a switching power supply using only feed-forward control, which is reflected in the duty ratio, by calculating the influence of these disturbances on the output voltage by detecting the load current and input voltage. Since only feed-forward control is used, there is no closed loop and there is no possibility of oscillation, and there is no degradation of stability due to changes in phase margin and gain margin when connected to capacitive and inductive loads. In buck converter, when the inductance of the circuit constant and the cutoff frequency of the capacitance is high, the transient characteristics equivalent to or better than those of the PID control is obtained, but other parameters were inferior to the PID control. Therefore, in this paper, we attempt to improve the transient characteristics by considering the AC component in the correction calculation of the influence amount. | |
