Description
technical field [0001] The invention relates to the technical field of electric power application, in particular to an active filter device with an infrared remote control function. Background technique [0002] The active filter device is a new type of power electronic device used to dynamically suppress harmonics and compensate reactive power. It can compensate harmonics that vary in size and frequency and reactive power that vary. It is composed of two main parts: command current operation circuit and compensation current generation circuit. The command current operation circuit monitors the current in the line in real time, converts the analog current signal into a digital signal, and sends it to a high-speed digital signal processor (DSP) to process the signal, separates the harmonic from the fundamental wave, and modulates it with pulse width ( PWM) signal form sends drive pulses to the compensation current generating circuit to drive the IGBT or IPM power module to g...
