Here a simple but efficient CFL inverter circuit, capable of diving a CFL, PL or tube light up to 20 watt. You can use this circuit to power up mobile chargers […]
Low voltage cutoff circuit for Inverters
Running inverters on battery drains the battery. This decreases the battery voltage. To regulate output voltage and to make it independent(upto a certain level) we use PWM based drivers like […]
H Bridge inverter power stage with passives
The above circuit I got from replies from edaboard. I had created a thread there on how can I drive a 2 pin primary transformer with H bridge configuration […]
