Abstract: A high-energy ignition coil, wherein a primary coil and a secondary coil are both wound around an iron core, these three constituting a transformer. The primary coil loop is provided with a switch controlled by an ECU. The spark plug is connected at one electrode to an end of the secondary coil, and is grounded at the other electrode. An on-board power supply supplies power to the primary coil via a DC booster, which boosts the DC voltage outputted by the on-board power supply before outputting. The other end of the secondary coil is either connected to the DC booster or grounded via a reversely connected diode. A current keeping device is connected in parallel with a serial branch of the secondary coil and the spark plug, working after the spark plug is turned on to keep the spark plug on.

Abstract: The present invention discloses an angular position sensor, which includes a rotor core as well as a stator core coaxially around this rotor core. Between the rotor core and the stator core is a first air gap, and inside the rotor core a second air gap, which is provided inside with a hard magnet. The stator core has a third air gap inside, which is provided inside with a magnetic flux sensing element. It is obvious that the present invention, by substituting the combination of the hard magnet and the rotor core for the design of ring magnet in the prior art, obtains the good linearity within a wider range.
