• Design and analysis of H-soft-switched converters

Publication Year: 1995, Page(s):255 - 261
Cited by:  Papers (6)  |  Patents (2)
| | PDF (348 KB)

An H-soft-switched cell is proposed to obtain soft switching in single-switch nonisolated DC-to-DC converters. The proposed cell provides constant-frequency loss-less switching. It may be regarded as a soft switch with a similar control circuit to that used in conventional PWM converters. Based on an equal area concept, a unified method for steady-state analysis is also proposed. The concept of eq... View full abstract»

• Analysis of conduction losses in inverters

Publication Year: 1995, Page(s):225 - 232
Cited by:  Papers (9)
| | PDF (456 KB)

A conduction-loss-evaluation method which is important in inverter design is presented. The method is based on the probability of inverter switching devices receiving ON signals. Since it does not require knowledge of the exact switching patterns of the power devices, the proposed method is especially useful for inverters in which the switching patterns cannot be predetermined. To show the general... View full abstract»

• SEPIC-derived three-phase sinusoidal rectifier operating in discontinuous current conduction mode

Publication Year: 1995, Page(s):239 - 245
Cited by:  Papers (6)
| | PDF (364 KB)

The paper presents a novel three-phase single-way sinusoidal rectifier to reduce supply current distortions and low power factor operations with diode bridge rectifiers. The circuit configuration is based on the cascade combination of a diode bridge and a single-ended primary inductor power convertor, in which a single power switching device provides the necessary control of the currents. If a sim... View full abstract»

• Simplified control strategy to improve AC-input-current waveform of parallel-connected current-type PWM rectifiers

Publication Year: 1995, Page(s):246 - 254
Cited by:  Papers (48)
| | PDF (624 KB)

A new control method for parallel-connected current-type PWM rectifiers for high-power applications is proposed. To reduce waveform distortion and transient oscillation of the AC supply current, state-feedback control of the AC-side LC filter is introduced. A new method of generating a PWM pattern suitable for the parallel connected rectifiers is proposed to obtain sufficient controllability with ... View full abstract»

• Losses in PWM inverters using IGBTs

Publication Year: 1995, Page(s):285 - 288
Cited by:  Papers (14)
| | PDF (280 KB)

The authors comment on the paper by F. Casanellas titled Losses in PWM inverters using IGBTs' (see ibid., vol.141, p.235-9, 1994). They suggest that Casanellas only gives a relatively coarse estimate concerning the reduction of the switching losses of discontinuous modulation in comparison to continuous modulation and expand on this subject. The original author replies to the comments View full abstract»

• Adapting a linear induction motor for the acceleration of large masses to high velocities

Publication Year: 1995, Page(s):262 - 268

| | PDF (560 KB)

The paper describes the features needed in the design of a linear induction motor which will accelerate a mass of 200 kg to 1200 m/s in a distance of 1500 m. The study throws new light on the fundamental principles of linear induction motors in general View full abstract»

• Computer application in the analysis of rectifiers and inverters

Publication Year: 1995, Page(s):233 - 238
Cited by:  Papers (4)
| | PDF (276 KB)

In industry, prior to the building of a prototype, it is often economical and useful to have a model. The paper describes a macromodel development technique for power converters using the transfer function approach. It is shown that even though SPICE micromodels are useful at the converter switch circuit' level, for complex circuits modelling at the system (macro) level is required. Analytical mo...

• Development of a model for representing dynamic behaviour of synchronous motor variable speed drives

Publication Year: 1995, Page(s):269 - 274
Cited by:  Papers (1)
| | PDF (400 KB)

The paper introduces a compact method for representing synchronous motors connected to a source of variable frequency. The model is based on a three-phase sinusoidal oscillator that represents the components of the magnetomotive force. The whole model is of seventh order and it accurately represents the dynamic behaviour of the motors. Even simulated dynamic behaviour, in which rapid frequency mod... View full abstract»

• Three-phase multifunctional battery energy storage system

Publication Year: 1995, Page(s):275 - 284
Cited by:  Papers (3)
| | PDF (556 KB)

A three-phase multifunctional battery energy storage system (BESS) is designed and implemented. When the utility power is in normal condition, the proposed BESS can be arranged to shave the peak load or charge the battery bank. In either case, since the load unbalanced, harmonic and reactive powers can be compensated through the proposed active power filter control, the power factor is maintained ... View full abstract»
