    摘要： An electric power converter comprising a plurality of reactors, a plurality of self quenching type switching elements, the reactors and switching elements being series-connected per one arm, and surge-absorbing snubber circuits connected in parallel to the switching elements respectively, the switching circuits being driven by gate drive circuits connected to respective gates of the switching elements to thereby convert a DC voltage into an AC voltage or convert an AC voltage into a DC voltage. The electric power converter further comprises: an apparatus for recovering energy accumulated on at least one side of the reactors and the snubber circuits and an apparatus for generating a DC source for supplying electric power to each of the gate drive circuits, on the basis of the recovered energy. In the electric power converter constituted by a plurality of self quenching type semiconductor switching elements connected in series, high efficiency is attained through reduction in size of the gate driver and electric power saving.

    摘要： A current-source power converting apparatus having a three phase AC-DC converter composed of self-extinction devices for converting an AC power furnished from an three phase AC power source into a DC power and a DC-AC inverter connected with the AC-DC converter through a DC reactor for re-converting the DC power into a three phase AC power to supply the re-converted power for a load. When the failure of the AC power source is detect according to one embodiment, the AC power source is detached from the AC-DC converter and a battery is connected between arbitrary two phases at the input end of the AC-DC converter. After that, the DC power of the battery is supplied for the DC-AC inverter intermittently by switching the corresponding self-extinction devices of the AC-DC converter and controlled by varying the duty ratio of the switching operation.

    摘要： An apparatus for controlling a current type inverter including a bridge circuit of bridge-connected self-extinguish elements triggered by pulse width modulation signals. A current is provided for applying a single or plural triggering pulses having a desired pulse width to those self-extinguish elements connected in series with the other self-extinguish elements forming the pairs in the bridge circuit and which other self-extinguish elements are turned on by the pulse width modulation signals. By the above manner of control, the current type inverter can generate output currents of sinusoidal waveform, and the value of the output currents can be controlled over a very wide range.

    摘要： In an arrangement having an electric power inverter 2 which applies a voltage to an AC motor 1 and a control unit 4 which calculates a voltage command value applied in PWM signals, detection use voltages Vup, Vvp and Vwp are applied in synchronism with PWM signal generation use carrier waves in the control unit 4 as well as motor currents iv and iv are detected in response to current detection pulses Pd in synchronism therewith. In a magnetic pole position detection unit 12, counter electromotive forces of the synchronous motor 1 are estimated from a relationship between the detection use voltages Vup, Vvp and Vwp and current difference vectors of the motor current to determine a magnetic pole position &thgr; through calculation. The determined magnetic pole position &thgr; is inputted to coordinate conversion units 8 and 11 and a motor speed detection unit 13. Thereby, a motor control device having a control characteristic of a good response property with no magnetic pole position sensor is provided for a control system of a synchronous motor.
