Title:
DC/DC CONVERTER AND CONTROL METHOD OF DC/DC CONVERTER
Document Type and Number:
WIPO Patent Application WO/2019/202745
Kind Code:
A1
Abstract:
The present invention suppressed influence of control due to the delay time in voltage switching between a plurality of different voltages. A DC/DC converter comprises: a main circuit including a switching circuit; a control unit that performs discrete control by discrete control toward a command value; and a switching signal generation unit that generates a switching signal that drives the switching circuit. The control unit calculates the pulse width ΔT(k) of the switching signal having the delay time Td as a parameter as an operation amount of discrete control performed every control period Ts. The switching signal generation unit generates a switching signal based on the pulse width ΔT(k) obtained by the calculation in the control unit. The main circuit switches the voltage level by driving the switching circuit based on the switching signal of the switching signal generation unit.
