Duty cycle & Pulse Width Modulation / ඉන්වටර් ක්‍රියාකාරිත්වය ඉගෙනගනිමු / Engineering Technology A/L

#Duty_cycle, #Pulse_Width_Modulation and #inverter operation Explained / ඉන්වටර් එකක් වැඩ කරන හැටි ඉගෙනගනිමු.
By systematically controlling duty cycle, pulse width and frequency, inverters can convert DC voltage to AC voltage very efficiently.
Modern Inverters are used to transform stable DC voltage into AC alternating voltage with a #pure_sine_wave, by methodical use of #digital_signals.
Use of pulse width modulation (#PWM) is well explained here in this video with fine animation work.
