The following diagram illustrates a 50W offline switching power supply circuit design. This circuit is powered by a MOSFET, specifically the BUZ80A/IXTP4N8 for a 220V AC voltage input and the GE IRF823 for a 110V AC voltage input. The...
When mains power is absent, relay RL2 remains in a de-energized state, supplying battery power to the inverter section through its normally closed contacts and switch S1. The inverter section consists of IC2 (NE555), configured in astable mode to...
If the ground of the Arduino is disconnected from the negative terminal of the power supply, current flows through the MOSFET, even when the switch is not closed. In an electronic circuit involving an Arduino and a MOSFET, maintaining a...
A simple 5-volt switching power supply electronic circuit project can be designed using the FAN302HL, a highly integrated PWM controller integrated circuit. This IC provides several features that enhance the performance of general flyback converters. The constant-current control of...
A standard 9V battery is considered depleted when its voltage drops below 7 volts. This switching regulator can extend the lifetime of a 9V battery. The circuit utilizes a switching regulator to optimize the energy usage of a standard 9V battery,...
A heatsink allows the TRIAC (TR1) to manage a maximum power of 350 watts. The neon lamp, II, will not activate the gate until the TRIAC begins conducting, and resistor R1 can be adjusted to set the desired lighting...
