摘要： A voltage boost converter includes: a main voltage boost portion that has a first switch and a first coil, and that raises output voltage of a direct-current power source by using counter electromotive force of the coil caused by the switch performing a switching action on the coil; and a subsidiary voltage boost portion which has a capacitor that adjusts potential difference between two poles of the switch by amount of electricity stored, and which reduces switching loss of the switch by adjusting the amount of electricity in the capacitor during the switching action, and which has a second switch and a second coil. The second coil is formed by winding a wire around at least a portion of a core formed of a magnetic body. The core is provided with a gap formed of a non-magnetic body. A core region formed of a magnetic body is adjacent to the gap.

摘要： A fault detector apparatus for a power converter in which a plurality of GTOs, functioning at a predetermined potential, are used. The apparatus includes a first fault-detecting circuit, coupled to the gate-cathode path of one of the GTOs, for generating a first fault signal when this GTO malfunctions, a second fault-detecting circuit, coupled to the gate-cathode path of another one of the GTOs, for generating a second fault signal when this GTO malfunctions, a photocoupler for transmitting a DC-isolated optical signal corresponding to the first fault signal, and one optical fiber system for transmitting a DC-isolated output signal, corresponding to the logical sum of the optical signal transmitted by the photocoupler and the second fault signal, to external circuits set at a potential different from the potential at which the GTOs are arranged. The fault-detecting circuits are provided in the same number as the GTOs. The fault-detecting circuits are coupled by the optical signals.

摘要： There are arranged an oscillator for generating a first pulse signal on which the AC output frequency of the inverter is based, a delay circuit for generating a second pulse signal delayed for a predetermined period of time from the first pulse signal, and a ring counter for generating responsive to the second pulse signal a phase reference signal corresponding in phase to the AC output of the inverter. An ON pulse is generated responsive to the second pulse and the phase reference signal and an OFF pulse responsive to the first pulse and the phase reference signal. A negative bias signal is generated following the OFF pulse. At the time of operation stop the negative bias signal following the ON and OFF pulses is applied to GTO thyristors simultaneously.
