Abstract: A new vehicle electrical system has a first lower voltage level and a second higher voltage level. The new vehicle electrical system comprises an ignition switch, a generator having an exciter circuit and a voltage controller, and a multi-chopper having several chopper stages. The voltage controller supplies energy to the exciter circuit via the ignition switch in order to adjust the first lower voltage level to a rated level of U1. The multi-chopper is connected between the battery and the generator, thereby adjusting the second higher voltage level to a rated level of U2 based on the number of chopper stages and their actuation.

Abstract: An inductive load drive device comprising a DC--DC converter circuit which has a coil (L) and switch (Sw) in series with a power source (E) and a capacitor (C) provided in parallel with the switch (Sw). The DC--DC converter produces a high voltage by a procedure in which the switch (Sw) is closed to apply the power source voltage to the coil (L) and then the switch (Sw) is opened to transfer the magnetic energy stored in the coil (L) to the capacitor (C). Using a permanent magnet (Mg), a bias in the direction opposite to that of the magnetic flux induced by the current is applied to the magnetic core of the coil (L) so as to increase the magnetic energy stored in the coil (L). Thus, a DC--DC converter circuit in which a capacitor is efficiently charged through a small-sized coil is realized, and an inductive load drive device having a small size and a light weight is also realized.

Abstract: A device for driving an electromagnet from a direct current source includes first and second circuits which are coupled in parallel to each other, and in parallel to a direct current source. The first circuit has a first switch, a solenoid coil, and a second switch all in series with one another. The second circuit has a third switch, a storage coil, and a fourth switch all in series with one another. A third circuit is provided which has a diode which is arranged to provide a current path from a junction between the storage coil and the fourth switch, to a junction between the first switch and the solenoid coil. In operation, during solenoid standby, the choke coil is caused to store electromagnetic energy. When the solenoid coil is energized, the switches are operated such that the energy stored in the storage coil is caused to quickly charge into the solenoid coil. The solenoid coil is maintained energized by operating the first switch in a chopper mode. To deenergize the solenoid coil, the switches are operated so that the energy in the solenoid coil is discharged into the storage coil. In this way, rapid deenergization is possible.
