Description

Technical Field

[0001] The utility model relates to the technical field of APF filters, in particular to a heat dissipation device for APF filters. Background Art

[0002] APF filter, namely active power filter, is mainly composed of two parts: command current detection circuit and compensation current generation circuit. The core function of command current detection circuit is to separate harmonic current component and reactive current component from load current, or detect the current command signal that needs to be compensated. This is usually achieved by using bandpass filter, low-pass filter, high-pass filter, FFT or instantaneous reactive power theory. The compensation current generation circuit generates the actual compensation current according to the command signal of compensation current obtained by command current detection circuit. The circuit is mainly composed of three parts: current tracking control circuit, drive circuit and main circuit. The main function of current tracking control circuit is to obtain the switching signal of each switch device in the main circuit through PWM and other control methods according to the error between the command signal of compensation current and the actual compensation current. The function of the drive circuit is to drive the switch device in the main circuit according to the switch signal to generate the actual compensation current.

[0003] The long-term heat dissipation of the existing APF filter will cause a lot of dust and debris to accumulate on the heat dissipation net. These impurities will not only affect the ventilation effect of the heat dissipation net, but may also block the holes of the heat dissipation net, resulting in a decrease in heat dissipation efficiency. When the heat dissipation performance of the equipment gradually decreases, it will cause the internal temperature of the equipment to rise, which may cause a series of performance problems, such as unstable operation and reduced efficiency.
