Power Electronics

What you'll learn

• Compare diodes, thyristors, MOSFETs, IGBTs and SiC and GaN devices, calculate conduction and switching losses, and design for junction temperature, gate drive and protection
• Model steady and transient heat flow in power modules, select cooling, predict power-cycling and capacitor lifetimes from mission profiles, and calculate failure rates and MTBF
• Analyze single-phase and three-phase uncontrolled and controlled rectifiers, quantify harmonics and power factor, and select harmonic mitigation including multipulse and active front ends
• Design gapped inductors by the area-product method, estimate core and winding losses at high frequency, design switching transformers, and select capacitors for ripple current and life
• Derive and design buck, boost and buck-boost converters, explain isolated and resonant converters and their control, and analyze efficiency and data center power delivery
• Derive averaged converter models and transfer functions, design voltage-mode and current-mode compensators for crossover and phase margin, and analyze load transients and input filter interaction
• Analyze PWM and multilevel inverters, apply space vector modulation, and explain grid-connected inverters under IEEE 1547 and UL 1741 and UPS topologies and efficiency
• Explain differential- and common-mode noise and EMI regulations, design input filters, limit turn-off overshoot with layout and snubbers, and apply layout principles
• Explain variable-frequency drive structure, V/f and vector control, affinity-law energy savings, braking, and reflected-wave, bearing-current and supply effects
• Apply power electronics to PV arrays with maximum power point tracking, wind turbines, battery storage with BMS, bidirectional dual active bridges and electric vehicle charging
• Compare AC and HVDC transmission, explain line-commutated and voltage-source converters and the modular multilevel converter, and describe FACTS devices
• Specify, design and plan verification of a complete converter, using loss budgets, switching-frequency trade-offs, hold-up, thermal and protection design
