Abstract: A semiconductor apparatus can block the voltage from the power source when the voltage from the power source reaches an excessive level, without requiring a larger chip size. Provided is a semiconductor apparatus including a power semiconductor element a gate of which is controlled in response to a control signal, an overvoltage detector configured to detect that a voltage at a collector terminal of the power semiconductor element reaches an overvoltage level, and a block unit configured to, in response to the detection of the overvoltage level, control the gate of the power semiconductor element to transition to an off-voltage. The semiconductor apparatus may further include a reset unit configured to, in response to that the control signal is input that turns on the power semiconductor element, output a reset signal for a predetermined period of time.

Abstract: A maximum value of a discharge current from a capacitor 13, detected by a primary-side current detection means 24 disposed at a grounded end of the capacitor 13, is controlled such as not to exceed a predetermined first control value Y1. The first control value Y1 is derived based on magnetic saturation of a primary winding 3, with the control being performed by controlling the on-off state of an energy injection switching means 20. As a result, magnetic saturation of the primary winding 3 can be prevented, and the reliability of an ignition apparatus which incorporates an energy injection circuit 6 can be increased.

Abstract: An ignition apparatus for an internal combustion engine is provided which includes a state-of-discharge determiner working to determine whether a center and a ground electrode of a spark plug are electrically conducting with each other or insulated from each other. When the center and ground electrodes are determined to be conducted with each other, the ignition apparatus alters controlled conditions of a high-frequency power supply which supplies a high-frequency power to the spark plug so as to decrease an average of a primary voltage outputted from the high-frequency power supply to the spark plug, thereby reducing an actual current flowing between the center and ground electrodes of the spark plug. This eliminates the risk of mechanical wear of the center and ground electrodes which usually arises from the flow of high current between the center and ground electrodes, thus resulting in an increase in service life of the spark plug.
