New sinusoidal pulsewidth-modulated invertor
Proceedings of the Institution of Electrical Engineers, 1975Sinusoidal p.w.m. invertors depend intrinsically for their operation on quite complex modulation processes. An in-depth study of these modulation processes is presented and the sources of possible operational problems are identified. These problems are shown to be manifest in low-frequency harmonic distortion and the possible existence of subharmonics ...

Invertor compensation in Germany
Institute of Legal Myongji UniversityIn Germany, company employees who make invention during the term of their employment, so-called “service inventions”, are subject to the German Act on Employee Inventions, which regulates the rights and obligations of both employees and employers. There are statutory guidelines as to the amount of compensation the inventor should be paid.

New 3-phase invertor with three thyristors
Proceedings of the Institution of Electrical Engineers, 1971A 3-phase invertor with three thyristors is described, superior in performance to its conventional counterpart. It is suitable for various types of load, including induction motors, in which a special winding permits further simplification of the circuit.

Proceedings of the Institution of Electrical Engineers, 1968
A 3-phase variable-frequency invertor is described. It is capable of controlling the output voltages by an on-off method. The commutation circuit is simple, and is so arranged that the invertor output voltages are independent of the load conditions. The triggering circuit and a protection scheme are also described.

Magnetic-film-controlled invertor and isolator
Proceedings of the Institution of Electrical Engineers, 1964The paper describes the principle of operation of an arrangement of conductors that is closely coupled to a magnetic film and can act as a signal invertor, modulator or isolator. The transmission characteristic is determined by the currents flowing in control conductors, which alter the film permeability.

Analytical methods for invertor-fed induction motors
Proceedings of the Institution of Electrical Engineers, 1975Invertor voltage waveforms for variable-frequency inductionmotor drives are frequently of a discontinuous form. One approach to steady-state analysis is to approximate periodic waveforms by a truncated Fourier series. As a less restrictive alternative, suitable for those commonly occurring cases where the piece-wise continuous sections can be described
