Abstract

The invention discloses a controllable stable current source, belongs to the control and adjustment field, and particularly relates to improvement of an existing controllable stable current source. The controllable stable current source can be used to accurately control a high power and large damping force magneto-rheological damper. The controllable stable current source comprises a judgment module, a field effect tube, a voltage stabilizer, an optical coupler, a single chip computer, a triode, an amplification circuit, a rectifying and filtering circuit and an adjustment circuit, and is characterized in that the judgment module, the field effect tube, the voltage stabilizer, the optical coupler, the single chip computer and the triode are sequentially connected, the optical coupler is connected with the amplification circuit, and the single chip computer and the rectifying and filtering circuit are connected with the adjustment circuit.

Description

technical field [0001] The present invention belongs to the field of control and regulation, and in particular relates to the improvement of a controllable constant current source. Background technique [0002] Constant current source, AC constant current source, DC constant current source, current generator, high current generator, also known as current source, steady current source, is a wide spectrum, high precision AC steady current power supply, with fast response, constant It has the advantages of high flow precision, long-term stable operation, and is suitable for various types of loads (resistive, inductive, capacitive), etc. It is mainly used to detect thermal relays, molded case circuit breakers, small short circuit breakers and production occasions where rated current, operating current and short circuit protection current need to be set. [0003] The existing magnetorheological damper is a widely used intelligent device designed according to the special properti...
