Active Harmonic Filter is a high-power, fast-switching electronic amplifier. Its job is to continuously monitor the electrical system and instantly inject equal but opposite "anti-harmonic" currents to cancel out the distortions. This demanding process generates a significant amount of waste heat, and managing this heat is paramount for several key reasons: 1. To Protect the Power Semiconductors (...
