The cost and quantity of parts necessary to develop the proposed 250 watt sine wave power inverter circuit is actually much less compared to a noisy square wave switching-type inverter circuit. Only an extra three or four tiny transistors, a some resistors and capacitors, a couple of pots and a small driver transformer are all […]

50 Watt Sine Wave UPS Circuit
The UPS detailed in this article can provide a power output of 50 watts consistently, at 110 volts with a frequency of 60 Hz. The output is fundamentally a sine wave that behaves exactly like standard mains home AC power for the load. An integrated power supply works like a battery charger. Even though the […]
Surge Protected Cheap Transformerless Hi-Watt LED Driver Circuit
The increased number of complaints from the readers regarding burning LEDs associated with my earlier posted transformerless 1 watt LED driver circuit, compelled me to solve the issue once for all. The power supply section of the circuit discussed here remains exactly identical to the previous configuration, except the inclusion of the “switch ON delay […]
