Description
technical field [0001] The invention relates to the field of power equipment, in particular to an active power filter. Background technique [0002] Active power filter is an advanced harmonic compensation device, which is widely used. The active power filter is connected in parallel to the grid to filter out the harmonic current flowing into the grid and reduce the harmonic content of the grid current. Usually, the active power filter uses a three-phase voltage type inverter circuit. Active power filters can output harmonic elimination signals to the grid to suppress or eliminate grid harmonics. The existing active power filter design is relatively traditional, and static electricity is often generated in its internal structure, which causes internal components to be affected by static electricity and cannot work normally. The anti-static ability inside the existing active power filter is average, and it is not convenient enough for practical use. Contents of the inven...
