摘要： Disclosed herein are a variety of different electrical system topologies intended to mitigate the impact of large intermittent loads on a 12 volt vehicle power distribution system. In some embodiments the intermittent load is disconnected from the remainder of the system and the voltage supplied to this load is allowed to fluctuate. In other embodiments, the voltage to critical loads is regulated independently of the voltage supplied to the remainder of the system. The different topologies described can be grouped into three categories, each corresponding to a different solution technique. One approach is to regulate the voltage to the critical loads. A second approach is to isolate the intermittent load that causes the drop in system voltage. The third approach is to use a different type of alternator that has a faster response than the conventional Lundell wound field machine.

A signal simulating a desired AC waveform is produced by a converter circuit at first and second converter output terminals. The converter circuit, responsive to respective switching signals applied thereto, selectively effects current paths between a juncture node and one of the first and second converter output terminals and between a common rail and the other of the first and second converter output terminals. A controller selectively generates control signals to the converter circuit and to a mechanism for varying the magnitude of the juncture node voltage, to create a predetermined waveform at the converter output terminals simulating the desired AC waveform.

摘要： A power device for an internal combustion engine is disclosed, which includes a rectification power section equipped with a voltage regulator and using an AC magneto driven by the internal combustion engine as a power supply therefor, a switch circuit including at least one MOSFET acting as a switching element and adapted to carry out short circuit between output terminals of the AC magneto, and an FET control circuit for repeatedly subjecting the MOSFET to on-off operation when an output voltage of the rectification power section is at a set level or below and keeping the MOSFET turned off when the output voltage exceeds the set level. The MOSFET is subjected to on-off operation during a low speed operation of the internal combustion engine to boost an output voltage of the AC magneto, to thereby provide a voltage for driving a load. On-off operation of the MOSFET is interrupted when an output voltage of the rectification power section exceeds the set level, so that loss due to switching of the MOSFET is reduced.
