What we have learnt

  • Power electronic converters are fundamental in transforming electrical power efficiently.
  • DC-DC converters can step down (buck) or step up (boost) voltages using PWM control.
  • Inverters convert DC to AC and utilize techniques like SPWM to reduce harmonics and enhance waveforms.

Key Concepts

-- PWM (Pulse Width Modulation)
A modulation technique used to control the average power delivered by an electrical signal.
-- Buck Converter
A DC-DC converter that steps down voltage from a higher level to a lower level.
-- Boost Converter
A DC-DC converter that steps up voltage from a lower level to a higher level.
-- IGBT (Insulated Gate Bipolar Transistor)
A power semiconductor device that combines the features of MOSFETs and BJTs, used for high power applications.
-- Sinusoidal Pulse Width Modulation (SPWM)
A modulation scheme that generates an output waveform closer to a sine wave, reducing harmonics.
