Abstract
Provided is multi-phase interleaving control in a power supply device, the control allowing the pulse widths ΔT of respective phases to overlap one another, so as to be adaptable to wideband pulse power control. In applying dead beat control to the multi-phase interleaving, constant current control is performed using combined current of the respective phase current values, and the pulse widths ΔT(k) is computed under this constant current control, thereby preventing variation of the pulse widths ΔT(k) between the phases, and achieving stable power control. Accordingly, the pulse power control becomes adaptable to wideband. Furthermore, wideband control is possible also in two-level pulse power control that performs control by switching at high frequency between High-level power and Low-level power.
