ACTIVE RECTIFIER CONTROLLER WITH REVERSE PROTECTION FOR BATTERY AND SOLAR CELL

Leave a Comment / Electronics News Updates /

This demonstration circuit is an active rectifier with reverse protection for batteries in automotive applications. The project is designed for 5A load current. Two clamping diodes, D1 and D2, are used on the board to protect the IC from overvoltage spikes at the input. The input supply range is 12V to 24V.  The active rectifier controller chip LT8672 controls an […]

In Part 1 of this series, we have reviewed solar cell performance, how to select and size the supercapacitor, requirements of supercapacitor charging circuits and charging IC characteristics. We will now use two case studies to illustrate these properties in detail. Case Study 1: Using a small solar cell indoors at low light, 100 lux,
