Abstract:
1. A predictive control system for a power converter circuit that transfers an input side power to an output side power by switching a switch to on-status or off-status, the predictive control system comprising: a sampling part that detects one or more of (a), (b), (c), (d) as two measurements in one cycle: a control part that wherein when the first sampling prediction value does not exceed the prescribed threshold value, the status of the switch is maintained, wherein when the first sampling prediction value exceeds the prescribed threshold value, the status of the switch is changed, wherein the power converter circuit is a DC/DC converter, and the first sampling measurement value is an actual measurement value of current that flows in the switch, and wherein the control part at least calculates the first sampling prediction value by a collinear approximation or a curve approximation based on two previous sampling measurement values.
