🚀 Episode 3 of the Variable Frequency Drive Knowledge Channel is now live! We’re breaking down a key component: The DC Intermediate Circuit – starring the Large Capacitor! 🎯 The mission of the DC filtering stage: ✅ Smooth out voltage ripple to provide the inverter with clean, stable DC voltage (ie. DC-Link or DC bus voltage). ✅ Serve as a transient energy buffer — delivering peak current to the inverter and absorbing regenerative energy from motor braking. 💡 Capacitors are the perfect fit for this role, due to their ability to store and release energy on demand. 🔍 Got thoughts or questions? We’d love to hear from you! 💬 What topics should we cover next?

⚡ dVOC Grid-Forming (Single-Phase Micro-Inverter) ⚡ Is it possible to operate a single-phase micro-inverter, with no ESS, as a GFMI? Absolutely! here’s the proof. My didactic PV inverter [https://lnkd.in/dvuZ43Yb ] is running a grid-forming algorithm, with dVOC as the primary controller. To avoid DC bus overvoltage, I embedded the inverter PQ capability directly before the inner current loop; It was quite tricky, but I eventually implemented a conditional-integration controller in the dq axes. The picture shows the dVOC GFMI synchronised with the real grid, delivering active power. #GridFormingInverter #dVOC #DispatchableVirtualOscillator #ConditionalIntegration #PowerElectronics #HandsOnLearning #HomeLabs

In a wind turbine, the slip ring unit in the nacelle-to-hub connection allows electrical power and communication signals to be transmitted between the stationary nacelle and the rotating hub. From your description, the slip ring in question is designed to supply and transmit: 400V AC → Usually for motor drives, pitch control actuators, or heaters in the hub. 230V AC → Auxiliary loads inside the hub (small devices, fans, sensors). 24V DC → Low-voltage control circuits, sensors, actuators, and PLC interfaces. CAN bus cable (Controller Area Network) → For high-speed communication between the hub pitch control system and nacelle main controller. ⚡ The warning stickers on the slip ring indicate high-voltage danger and a safety restriction against improper handling. This component is critical because without it, the hub (which rotates with the blades) cannot receive power or communicate with the main controller inside the nacelle.
