The invention belongs to converters technical field, it relates to a kind of soft electrification circuit of single phase rectifier, particularly relates to a kind of soft electrification circuit of the single phase rectifier based on thermistor.
Background technology
For the Technics of Power Electronic Conversion device containing diode rectifier circuit of ac power supply, it is necessary to consider the soft problem that powers on, otherwise will break down at power up phase Technics of Power Electronic Conversion device. The conventional many employings of the current limliting measure that powers on unloading phase increase the method for current limliting resistance in the line, specifically comprise four kinds of methods:
(1) DC side or exchange live wire on series limiting resistor, the current limliting when powering on, but power on terminate after time utilize rly. automatically to excise;
(2) series connection PTC thermistor, utilizes its positive temperature profile, the current limliting when powering on, but utilizes rly. automatically to excise after the end that powers on;
(3) series connection NTC thermistor, utilizes its negative temperature characteristic, the current limliting when powering on, but retains on the line when powering on and terminate rear;
(4) reasonable circuit is set, after powering on and terminating, adopts thyristor or other power device such as power on resistance, thyristor or other power device of IGBT short circuit still to connect in the line.
The problem of first two method is: bring secondary current shock problem when resistance excises. The problem of the third method is: be only suitable for the application scenario that load power is less than 200W. For this reason, for high-power applications occasion, it is necessary to improved by the existing current limliting circuit that powers on, power-on impact current problem is thoroughly solved. The problem of the 4th kind of method is, when thyristor flows through electric current, forms pressure drop, produces to consume, reduces the efficiency of whole circuit, cause insoluble heat dissipation problem.
