Problems solved by technology

The former cannot stabilize the load current fluctuation caused by the impedance change caused by the self-heating phenomenon, and the latter cannot solve the load current fluctuation caused by the slow voltage change, so the current stabilization effect is not good
In addition, the load characteristics are various, and it is difficult to make a series of products, so the application of the above-mentioned current stabilizer is limited.

Description

technical field [0001] The invention relates to a device for rapidly stabilizing an alternating current within a power frequency cycle, which belongs to alternating current stabilizing equipment. Background technique [0002] During the user's power consumption process, there is a large deviation between the effective value and waveform of the current and some predetermined indicators, so the current needs to be stabilized. At present, a current stabilizer is generally used to stabilize the effective value of the current. One of the current stabilizers is to stabilize the load current by stabilizing the load voltage or to serially insert a reactor (commonly known as a ballast) in a circuit that requires a stable current to limit and stabilize it. load current. The former cannot stabilize the load current fluctuation caused by the impedance change caused by the self-heating phenomenon, and the latter cannot solve the load current fluctuation caused by the slow voltage change...
