  "textContent": "Provided is a control apparatus for a supercharged internal combustion engine, which can favorably achieve a good balance between prevention of overheat of a catalyst disposed an exhaust passage and suppression of turbo lag, in a case in which a fresh air blow-through is generated through a combustion chamber from an intake passage to an exhaust passage. A turbo supercharger (22), an exhaust bypass passage (36), a WGV (38) capable of switching the opening and closing of the exhaust bypass passage (36), and variable valve operating mechanisms (46, 48) capable of changing a valve overlap period are included. The valve overlap period is shortened so that the fresh air blow-through amount Gsca becomes equal to or smaller than a predetermined blow-through determination value Gjudge when the blow-through amount Gsca is larger than the blow-through determination value Gjudge. The WGV (38) is opened when the blow-through amount Gsca is still larger than the blow-through determination value Gjudge after the valve overlap period has been shortened.",
