Mod 1: Adding a Crowbar Overvoltage Protection

On the top diagram, locate the 7805 output trace (pin 3). Insert a 6.2V Zener diode and an SCR (e.g., C106D) between the output and ground. The top view shows where to cut the trace – immediately after the output capacitor. Insert a 6

PWM Controller: Integrated circuits like the OB2263, which manage the switching frequency to ensure a steady output.
