EMC (Electromagnetic Compatibility) testing for an Active Harmonic Filter AHF is critical and non-negotiable. An AHF(APF) is a power electronics device (like a high-frequency inverter) that injects canceling currents into a noisy electrical system. If poorly designed, it can become a significant source of electromagnetic interference (EMI) itself, disrupting other equipment. Conversely, it mu...
The Problem: Variable Speed Drives Generate Harmonics What is a Variable Speed Drive (VSD/VFD)?A Variable Speed Drive (VSD), also commonly called a Variable Frequency Drive (VFD) or Adjustable Speed Drive (ASD), is an electronic device that controls the speed and torque of an AC electric motor by varying the motor's input frequency and voltage. How Do They Cause Harmonics?The internal design of a ...
Introduction As global energy demand continues to rise, distributed photovoltaic (PV) generation has emerged as a key solution for achieving sustainable and decentralized power. In Latin America, Colombia has been steadily expanding its renewable energy capacity, with the city of Medellín—a vibrant urban hub surrounded by the Andes Mountains—leading the way in solar adoption. Th...
