In last century 90 generation of when on has appeared has high pressure frequency Manager of using and development, for such of electrical equipment main of work principle is relies on hydraulic of using way, in motor in the appeared of series of of device of combination, important of using is for speed of regulation, such from essentially for equipment of regulation role, guarantee equipment of using efficiency, thereby guarantee has productivity of improve.

In the use of high-voltage inverter, progressive marketing, electronic use patterns in a changing market, contributed to the electrical industry in the energy conversion in constant development, address the root causes of the electrical industry efficiency, meet the people's needs.

For high pressure frequency Manager of using way has many kind of, in using of process in the attention of is frequency Manager of using features, can will grid of voltage gradually of reduced, then in for and low pressure frequency Manager of using and links, such on to promote power of using, two kind of equipment of effective of links is using high pressure frequency Manager of important of using method, can effective of for high pressure of reduced measures.

So in domestic of electrical equipment of using technology in the, most important of things is for high pressure frequency Manager of using technology, such can very precision of for voltage of regulation, also can for speed of reduced, range of narrow, important of is can will workload changed small, maintenance equipment of using features, such can from technology Shang beyond has those old of mode, also has good of regulation of effect. Such technological development is more mature, it is most easy to use technology in the conversion of the high and low pressure, and save money by putting, very late, are important industry types.
