IC 555 output waveformД¬onsequences if the duty cycle is not 50% for an inverter:

We can witness from the oscilloscope that we are getting very close to 50 % duty cycle and also getting around 58Hz as per our calculation (good enough for 50/60Hz low power devices). equal amount of ON and OFF time is very important for an inverter. One important factor we should always take care is the duty cycle. In real life we will get around 55 Hz (depending on tolerance of components used) which is good enough for low power application like chargers, CFL lamps, table fans, tube lights, incandescent lamps etc. Using these values we can achieve close 50Hz and 50% duty cycle. So, after many calculations we concluded the values for the two resistors as 4.7K and 120K and the capacitor value as 0.1uF. The values are chosen carefully to meet the 50Hz and 50 percent duty cycle requirement as close as possible.

Here we are utilizing 4.7K and 120K values for resistors and we have chosen 0.1uF value for capacitor. The frequency of the IC 555 is determined by the two resistors and one capacitor. The oscillations will be amplified by the next stage using MOSFETs.Д¬alculating resistor and capacitor values: The oscillator circuit converters DC current from battery in to AC current at lower power level the frequency and duty cycle are determined at this stage. Moreover the 555 timer is already a popular IC among the new comers of electronics and also among much experienced hobbyists and all would find easy to work with IC 555.Д«y looking at the circuit you would have got an idea how easy the circuit is, now letвЂ™s deconstruct each stage and explore.ДЄny power inverter circuit has the following 3 stages: The IC 555 can handle it like piece of cake. Inverter is also a timing based circuit whose frequency and duty cycle are important parameter. There are many inverter circuits using IC based oscillators around the internet, but none can beat the popularity of IC 555 which has tons and tons of applications in timing based circuits.
