Abstract

The invention provides a single-phase fan speed regulation solid-state relay. The single-phase fan speed regulation solid-state relay comprises an external control module, an input module, a driving module and a power assembly module, the input module is connected with the external control module and the driving module. The driving module is connected with the input module and the power assembly module. The power assembly module is connected with the single-phase alternating-current power supply and the fan motor. The external control module is used for providing a plurality of selectable gears, each gear corresponds to a control signal, and different control signals correspond to different fan motor load voltages; the input module is used for accessing a control signal sent by an externalcontrol module and sending the control signal to the driving module; the driving module is used for receiving the signal sent by the input module, processing the signal and sending the signal to thepower assembly module; and the power assembly module is used for receiving the signal sent by the driving module and controlling the rotating speed of the fan motor through the signal.

Description

technical field [0001] The invention relates to a solid-state relay, in particular to a speed-regulating solid-state relay for a single-phase fan. Background technique [0002] At present, the fan speed control circuit is mostly implemented by changing the conduction angle of the thyristor. By changing the conduction angle of the thyristor, the effective voltage on the load of the fan can be changed to realize the change of the fan speed. The advantage of this method is that the circuit is simple, the control is convenient, and the continuous adjustment of the fan speed can be realized through a potentiometer. The disadvantage is that due to the change of the conduction angle of the thyristor, the current of the fan is discontinuous, and the fan will have relatively large vibration when starting and when the speed is low, and it will not be stable. At the same time, there will be a relatively large 100Hz current during operation. Noise (twice the AC mains frequency). [0...
