Abstract
The utility model relates to a transducer, in particular to an energy feedback-typed high voltage transducer with low harmonic and high power factor, which takes an insulation gate semiconductor high speed switch power module (IGBT) as a main component. The AC input of the transducer is sequentially connected with a first filter unit, a power factor revising unit, a second filter unit, and an inverter unit by a high voltage breaker, and is finally output to an output terminal load; wherein, the insulation gate semiconductor high speed switch power modules (IGBT) adopted by the inverter unit are directly connected with each other in series. As the IGBT is taken as the main component of the transducer, and the power factor revising unit is increased between two filter units, the machinery adopting the transducer has large speed regulation range, small loss, wide applicable load range, is easy to implement the positive and reversed rotation shift and to constitute an automatic control system, with small starting current, and is used for the sites of frequent starting and braking, and high requirement to harmonics and power factors.
Description
Affiliated technical field
The utility model relates to a kind of frequency converter, and especially a kind of employing Iusulated gate semiconductor speed-sensitive switch power model (IGBT) is the low harmonic wave High Power Factor high voltage converter of critical piece.
Background technology
A large amount of in the industrial production the humorous demanding machinery of power factor that involves is all needed to carry out speed regulation.And the speed regulating device that use in the prior art have increased the complexity of system, have also caused a large amount of wastes of the energy.Therefore, people wish to adopt the ac motor speed control system to replace dc motor speed-regulating system always, and have carried out a large amount of research and developments.
Developed multiple ac motor speed control device for many years, as: stator variable voltage speed control, pole changing, slip regulating speed, electromagnetic coupler speed governing, tandem control, commutator machine speed governing etc.Though succeeding in developing of these governing systems obtained certain achievement, but still exist shortcomings such as speed adjustable range is narrow, loss is still bigger than normal, power factor is low, suitable load surface is narrow, thereby limited the application of these Alternating Current Governor Systems.
The utility model content
The purpose of this utility model be to provide a kind of speed-regulating range width, loss little, be applicable to and involve the low harmonic wave High Power Factor high voltage converter that the demanding occasion of power factor is used humorous.
The technical solution of the utility model is achieved in that the interchange input 1 of frequency converter is through the primary cut-out 2 and first filter unit 3, (English is Power FactorCorrection in power factor correction, be abbreviated as PFC, also claim harmonic) unit 4, second filter unit 5, inversion unit 6 connects in turn, outputs to output load 7 at last.Wherein the Iusulated gate semiconductor speed-sensitive switch power model that adopts in the inversion unit 6 is directly series connection each other.
The beneficial effects of the utility model are:
Adopting IGBT is that the speed adjustable range of low harmonic wave High Power Factor high voltage converter of critical piece is big and continuously, realize that easily forward and backward is switched and the formation automatic control system, starting current is little, can be used for Fraquent start, braking and the humorous power factor that involves is required extra high occasion.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is a converter circuit schematic diagram of the present utility model.
Among the figure 1, exchange input, 2, primary cut-out, 3, first filter unit, 4, power factor correction unit, 5, second filter unit, 6, inversion unit, 7, the output load.
Embodiment
In Fig. 1, the interchange of the frequency converter input 1 process primary cut-out 2 and first filter unit 3, power factor correction unit 4, the second filter units 5, inversion unit 6 connects in turn, outputs to output load 7 at last.Wherein the Iusulated gate semiconductor speed-sensitive switch power model that adopts in the inversion unit 6 is directly series connection each other.For high voltage converter of the present utility model, it exchanges input 1 is the power frequency of 3-10KV, makes that this frequency converter goes for the humorous power factor that involves is required extra high occasion owing to added the PFC correcting unit in frequency converter.
