Patent TW-504890-B (TW)
Title: Power unit
Inventor: ASAI KOICHI
IPC: H02M5/257
Filed: 2001-02-01
Granted: 2002-10-01
Abstract: A power unit is provided which can perform stable feedback control by reducing a feedback gain, and sufficiently cope with fluctuations in the output voltage occurring according to fluctuations in the input voltage caused by fluctuations in the rotational speed of an engine. A pair of variable control bridge circuits are connected to three-phase output windings of a three-phase generator driven by the engine, and connected in an antiparallel manner to each other to form a cycloconverter for generating a single-phase alternating current to be supplied to a load. A voltage-detecting circuit detects a voltage of the three-phase alternating current. An effective voltage value-calculating circuit calculates an effective value of the voltage of the alternating current. A reference sinusoidal waveform-forming circuit generates a voltage of a reference waveform for controlling the single- phase alternating current. A reference effective voltage value-generating circuit generates a reference effective voltage for controlling the single-phase alternating current. A firing angle control device controls the pair of variable control bridge circuits such that the pair of variable control bridge circuits alternately switch to operate every half a repetition period of the single-phase alternating current, so as to make the effective value of the voltage of the single-phase alternating current closer to a value of the reference effective voltage, and at the same time, make the voltage of the single-phase alternating current closer to the voltage having the reference waveform.
