Abstract
The invention discloses a direct current transform control device of a transducer, which belongs to a control device, and is capable of meeting the electricity consumption requirement of portable entertainment equipment of a large airliner. The direct current transform control device comprises a current control loop and a voltage control loop, wherein the current control loop is composed of a current sensor (3) which is connected with a direct current/direct current (DC/DC) convertor (6) through a current adjuster (4) and a pulse width adjuster (5) orderly; the voltage control loop is composed of a voltage sensor (1) which is connected with the output end of the DC/DC convertor (6) through a voltage adjuster (2), the current adjuster (4) and the pulse width adjuster (5) orderly. The direct current transform control device of the transducer is fast in transient response, good in stability, high in accuracy of output voltage and good in output waveform, has an output current-limiting protection function, and is used for supplying power to the entertainment equipment of the airliner.
Description
Technical field
The present invention relates to a kind of control device, relate in particular to a kind of frequency converter DC converting control device.
Background technology
Frequency converter is the three-phase 115V/200V on passenger plane, 400Hz three-phase alternating current to be converted to a kind of power-supply device of 115V, the single-phase sine wave alternating current of 60Hz.At present, the defects such as airborne frequency converter exists that output voltage stability is poor, transient response speed is slow, poor stability, overcurrent protection are bad, frequency-converter power loss height, can not meet the electricity consumption requirement of airliner portable entertainment device.
Summary of the invention
In order to overcome the defect existing in prior art, the present invention aims to provide a kind of frequency converter DC converting control device that can meet airliner portable entertainment device electricity consumption requirement.
To achieve these goals, the present invention by the following technical solutions: it comprises current regulator and voltage control loop; Described current regulator is formed by connecting by current regulator, pulse width regulator and DC/DC converter successively by the current inductor being connected with DC/DC converter, and described voltage control loop is formed by connecting by voltage regulator, current regulator, pulse width regulator and DC/DC converter successively by the voltage sensor being connected with DC/DC converter output terminal.
Compared with the prior art, the present invention is owing to having adopted technique scheme, therefore owing to having adopted, take the dicyclo control structure that current regulator is outer shroud as interior ring, the voltage control loop of take; Therefore not only can to carry out regulating and controlling output voltage by voltage control loop be set point, make it not to change with the fluctuation of input voltage, but also can improve by current regulator the dynamic responding speed of system.Itself and traditional output voltage monocycle reponse system comparison, system not only has the stability of transient response and height fast, and output voltage precision high, there is the inherent advantages such as output current limiting ability.
Accompanying drawing explanation
Fig. 1 is structure of the present invention.
In figure: voltage sensor 1, voltage regulator 2, current inductor 3, current regulator 4, pulse width regulator 5, DC/DC converter 6.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
As shown in Figure 1: current regulator is formed by connecting with DC/DC converter 6 by current regulator 4, pulse width regulator 5 successively by the current inductor 3 being connected with DC/DC converter 6, described voltage control loop is formed by connecting with DC/DC converter 1 by voltage regulator 2, current regulator 4, pulse width regulator 5 successively by the voltage sensor 1 being connected with DC/DC converter 6 outputs.
Voltage regulator 2 and current regulator 4 in above-described embodiment are pi regulator, the output of voltage regulator 2 compares as the inductive current of given value of current signal and feedback, make inductive current (mean value) follow given signal, the output of current regulator 4 and sawtooth signal compare and obtain pwm signal.
