EEEN60192 - Principles of Power Electronic Converters
Availability - Course (Compulsory/Elective)
Aims
The unit aims to:
Provide an overview of the operating principles and characteristics of the main types of power electronic converter, including the methods for the calculation of steady-state operating conditions and component values.
Brief Description
The three main classes of power electronic converter (DC-DC, AC-DC and DC-AC) will be described in turn including the idealised waveforms and the calculation of steady-state operating conditions. The characteristics of the principal semiconductor device types will be described. Simple inductive switching waveforms will be studied along with the calculation of device losses.
Learning Outcomes
Students will be able to:
Knowledge and understanding
- Sketch circuit diagrams, steady-state waveforms, and explain the operation of the buck, boost and buck/boost converters in the continuous and discontinuous conduction modes. Derive voltage conversion ratio expressions for each converter, and undertake calculations of circuit components and operating conditions.
- Sketch circuit diagrams, steady-state waveforms, and explain the operation of single-phase and three-phase diode rectifiers assuming large DC filter inductors. Derive expressions for the average output voltage including the effects of source inductance. Undertake Fourier analysis of the AC input currents and the calculation of current total harmonic distortion and power factor.
- Sketch circuit diagrams, steady-state waveforms, and explain the operation of single-phase PWM rectifier, including the calculation of the phasor diagram and the waveform harmonics. Explain the principle of square-wave switching and sinusoidal pulse-width modulation, including bi-polar and uni-polar modes of operation.
- Sketch circuit diagrams, steady-state waveforms, and explain the operation of single and three-phase voltage sourced inverters, including the calculation of waveform harmonics.
- Describe the characteristics, typical ratings and applications of the power MOSFET, IGBT and GTO. Sketch and describe inductive switching waveforms and calculate switching losses. Undertake thermal calculations.
