Title:
CONTROL DEVICE OF POWER CONVERTER
Document Type and Number:
WIPO Patent Application WO/2019/159504
Kind Code:
A1
Abstract:
According to the present invention, a subtraction unit (30) calculates a voltage deviation of an output voltage (Vout) of a DC/DC converter (7) from a target voltage (Vf). An FB control amount calculation unit (40) calculates an FB control amount (Cfb) in each control period. The FB control amount calculation unit (20) calculates an FF control amount (Cff) in a direction, in which a change in the output voltage (Vout) is impeded, in a control period in which it is detected by an FF control determination unit (10) that the output voltage (Vout) crosses the target voltage (Vf). A switching control signal generation unit (60) generates a control signal for the DC/DC converter (7) in order to control the output voltage (Vout) according to an addition value of the FF control amount (Cff) and the FB control amount (Cfb).
