Abstract
The invention relates to a controller for a direct-current variable-frequency compressor, which comprises a printed circuit board, and a rectifying circuit, an inverter circuit, a control circuit and a switching power supply circuit which are arranged on the printed circuit board. The invention reasonably arranges the rectification circuit, the inverter circuit, the control circuit and the switching power supply circuit on the printed circuit board, reduces the interference among the circuits of the controller, avoids the faults of failure, burning out and the like of the controller caused by the interference and improves the reliability of the controller.
Description
[technical field]
The present invention relates to a kind of controller, particularly a kind of controller that is used for DC frequency-changeable compressor.
[background technique]
At present; The controller that is used for DC frequency-changeable compressor; It mainly comprises: rectification circuit, inverter circuit, control circuit and switching power circuit; Rectification circuit and inverter circuit serial connection; Rectification circuit changes into the direct current of constant voltage with the single-phase alternating current of 220V/50HZ, and inverter circuit is with direct current conversion and the threephase AC that becomes DC frequency-changeable compressor to need, and control circuit output control signal is with the work of control inverter circuit; The working power signal that switching power circuit is changed the forceful electric power source signal and output belongs to light current is to control circuit, and switch power can be obtained the forceful electric power source signal from the input end of rectification circuit or the output terminal or the inverter circuit output terminal of rectification circuit.Wherein, rectification circuit and inverter circuit belong to the forceful electric power circuit, and control circuit belongs to the light current circuit, and switching power circuit belongs to forceful electric power and light current circuit synthesis body.Because this five partial circuit is placed on the same printed circuit board and has electromagnetic interference problem, generator controller such as lost efficacy, burnt out at fault easily.
[summary of the invention]
The technical problem that the present invention will solve provides a kind of safe and reliable controller that is used for DC frequency-changeable compressor.
Above-mentioned technical problem solves through following technological scheme:
A kind of controller that is used for DC frequency-changeable compressor; It comprises a printed circuit board (PCB) and is located at rectification circuit, inverter circuit, control circuit and the switching power circuit on this printed circuit board (PCB); It is characterized in that; Each other the rectification circuit of serial connection does not form the circuitous flow direction with inverter circuit by electric current and arranges, control circuit connection and near the output terminal of switching power circuit.
Distance between control circuit and rectification circuit, the inverter circuit is all greater than 10mm.
Visible by technique scheme; The present invention on printed circuit board (PCB), reasonably arrange rectification circuit, inverter circuit, control circuit and switching power circuit reduce the interference between controller circuitry, avoid because of disturbing generator controller to lose efficacy; Fault such as burn out, improve the reliability of controller.
[description of drawings]
Fig. 1 is a structural representation of the present invention.
[embodiment]
As shown in Figure 1; A kind of controller that is used for DC frequency-changeable compressor; It comprises a printed circuit board (PCB) and is located at rectification circuit, inverter circuit, control circuit and the switching power circuit on this printed circuit board (PCB) that the rectification circuit of serial connection and inverter circuit do not form the circuitous flow direction by electric current and arrange minimizing loop interference between two forceful electric power circuit modules each other; Control circuit connects and near the output terminal of switching power circuit; Improve control circuit stability, the distance between control circuit and rectification circuit, the inverter circuit is all greater than 10mm, and forceful electric power circuit module and light current circuit module keep certain distance to place; To reduce the interference between forceful electric power circuit module and light current circuit module, improve the reliability of controller.
The present invention is not limited to the foregoing description, based on simple replacement the foregoing description, that do not make creative work, should belong to the scope that the present invention discloses.
