In this post I will explain a very basic 12V to 220V AC inverter design using IC 555 as the oscillator stage, for generating a 50Hz frequency to the MOSFET driver stage of the inverter. We have used a center tap transformer for this design which effectively converter the battery 12V into 220V AC 50 […]

Pure Sine wave Inverter using IC 555
In one of my earlier posts we elaborately learned how to build a SPWM generator circuit using an opamp and two triangle wave inputs, in this post we use the same concept to generate the SPWMs and also learn the method of applying it within a IC 555 based inverter circuit. Using IC 555 for […]
Modified Square Wave IC 555 Inverter Circuit
The proposed IC 555 based modified square wave inverter circuit generates accurately spaced PWM pulses which imitates a modified sine wave very closely and thus can be considered as good as its sine wave counterpart design. Here we use two stages for creating the required PWM pulses, the stage comprising the ICs 741 and the […]
Transformerless IC 555 Inverter Circuit
The design showing below depicts a simple yet very effective 4 MOSFET n channel full bridge IC 555 inverter circuit. The 12 V DC from the battery is first converted into 310 V DC through a ready made DC to AC converter module. This 310 VDC is applied to the MOSFET full bridge driver for […]
IC 555 Full Bridge Inverter Circuit
The idea presented belowcan be considered as the simplest IC 555 based full bridge inverter circuit which is not only simple and cheap to build but is also significantly powerful. The power of the inverter may be increased to any reasonable limits y suitably modifying the number of mosfets at the output stage. How it […]
Understanding SCR or Thyristor Controlled Inverter Circuit
So this circuit changes 12V DC power from a battery into 115V AC power at 60Hz, 230V 50Hz, depending on the transformer secondary specifications. It can drive small AC electrical items up to 100 watts total power. It uses two UJT transistors to make the 60Hz timing speed and two power SCRs or transistors to […]
