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...
1. Why Do SVGs Generate Harmonics? Unlike ideal components, the real-world power electronic switches (IGBTs) in an SVG do not switch sinusoidally. They use Pulse Width Modulation (PWM) to synthesize a sinusoidal output current. This switching action is the primary source of harmonics. PWM Switching Frequency Harmonics: The output voltage of the SVG's H-Bridge inverters is a series of high-fre...
SVG Parallel Operation Test via CAN Communication Test Objective This test aimed to verify the performance and stability of multiple SVG (Static Var Generator) units operating in parallel via CAN communication when internal CTs are not used. Specifically, eight SVG modules were tested to evaluate their operation, communication reliability, and reactive power compensation consistency under CAN-base...
As electric vehicle (EV) adoption continues to grow across Europe, Italy is accelerating its efforts to expand charging infrastructure. To support this transition, YTElect recently delivered 300 units of 22 kW three-phase AC charging stations to an Italian distributor — a major step toward strengthening the country’s public and private charging network. This deployment underscores YTEl...
