This project aims to design and develop a modular monitoring system for a LiC supercapacitor array, incorporating PCBs A and B for voltage sensing on either side of the array, and PCB C for central control. PCBs A and B will measure cell voltages, communicate data via I2C, and feature activity/status LEDs, powered directly from the array. PCB C will aggregate data, managing over/under voltage, overcurrent, and balancing. The goal is a compact, efficient solution to ensure the array's safety and longevity.

This project is focused on designing a highly efficient PCB for a switching power supply using a robust selection of electronic components. Our design leverages a flyback topology featuring a ferrite transformer (options EE25 or EE33), a PWM integrated circuit (TL494, SG3525, or UC3842), and a power MOSFET (IRF840 or a similar alternative) for effective high-voltage switching. Fast and reliable rectification is ensured by using a Schottky diode (MBR20100 or FR107) along with a rectifier bridge built from four 1N4007 diodes or a dedicated 4A bridge. Key stabilization and regulation components include the TL431 reference regulator and a Zener diode for precise voltage control in critical areas. For input and output filtering, the design incorporates electrolytic capacitors (470 µF, 25 V for output and 400 V, 100 µF for input) and ceramic capacitors (ranging from 1 nF to 100 nF) to limit high-frequency noise. Additional safety and operational features are provided by an NTC (soft-start thermistor) to prevent current spikes, various resistors (from 1 Ω to 100kΩ), an optocoupler (PC817) for signal isolation, a switch, and a protection fuse. Before moving forward with a finalized PCB layout and schematic details, we need to clarify a few design choices: 1. Transformer Choice: Would you prefer using the EE25 or the EE33 ferrite transformer variant as the heart of the switching power supply design? This detailed approach ensures that the power supply not only meets rigorous performance and safety standards but also supports a reliable and scalable solution for various electronic applications. #PCBDesign #SwitchingPowerSupply #Electronics #SMPS #PowerElectronics #FlybackConverter #CircuitDesign #ElectronicsComponents
