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.
