Abstract: A controller (20; 21; 22) used to control a flyback switching mode power supply (10; 11; 12). The flyback switching mode power supply (10; 11; 12) is constructed to charge a capacitor (C), and includes a rectifying device (RD), a series arrangement of a switch (SW1) and a primary winding (L1) of a transformer (T) for receiving an input voltage (Vin), and a secondary winding (L2) of the transformer (T) for charging the capacitor (C) via the rectifying device (RD) to an output voltage (Vout). The controller (20; 21; 22) is configured to sense the output voltage (Vout) and to turn on the switch (SW1) when the change of the output voltage (Vout) over time becomes smaller than a predetermined threshold (dth). By using the controller (20; 21; 22) to sense and use the output voltage (Vout) across the capacitor (C) to turn on the switch (SW1), a controlled flyback switching mode power supply (10; 11; 12) that makes use of voltage control is realized.

Abstract: An ignition apparatus includes a blow-off determining unit. The blow-off determining unit determines, when a secondary electric current drops below a predetermined threshold value Ia during a determination period, that blow-off has occurred; the determination period is a predetermined time period ΔT from the start of a spark discharge by a main ignition circuit. Further, when it is determined that blow-off has occurred during a main ignition (full-transistor ignition), it is controlled to perform a continuing spark discharge after the main ignition in a next cycle. Moreover, a secondary electric current command value I2a in performing the continuing spark discharge is set to an electric current value that is obtained by adding a predetermined electric current value α to the predetermined threshold value Ia used in the blow-off determination. Consequently, in the next cycle, it is possible to reliably prevent blow-off, thereby reliably preventing a misfire.
