Course details

This course introduces students to the fundamentals of power electronics with a clear focus on understanding, designing, and controlling switching power converters. It begins with an explanation of switching devices, comparing ideal and practical behavior, and covers their control, gate drive circuits, and protection methods to ensure safe operation. The course then explains reactive elements such as inductors and capacitors, including how to select and design them for power electronic circuits. Various switching power converter topologies are studied in detail, along with their working principles and steady-state operation. Students learn how to develop steady-state and dynamic models of converters for analysis and design. The performance of converters, including efficiency, regulation, and response, is thoroughly discussed. A review of linear control theory is provided to build a foundation for control applications. The course then focuses on closed-loop control of power converters to achieve stable and accurate output. Practical design considerations are emphasized throughout the course. Finally, students apply their knowledge through sample designs and construction-based projects, helping them connect theory with real-world applications.

Questions and Answers

Q: You're reviewing a power stage GA and the spec calls out IEC symbols. The drawing shows the input EMI filter earth tied to DC- via a capacitor, but the datasheet text says "protective earth isolated". You're stuck and google "SMPS EMI filter Y-capacitor symbol tied to DC negative meaning". What do you do at DFMEA review?

A: A drags DC- into PE without a formal earthing concept; that breaks ISO 26262 assumptions fast. B is the only move that respects traceability — drawing and text conflict, so DFMEA can't guess intent. C trusts prose over a symbol that drives leakage and fault paths. D invents a hybrid condition that no test plan will ever cover.

Q: Back-of-envelope check before sign-off. The buck runs 12 V to 1.2 V at 40 A, 400 kHz, single-phase. You're searching "estimate buck converter inductor ripple current automotive". What ripple current is defensible for DFMEA thermal stress screening if L is 220 nH?

A: A forgets the tiny inductance; frequency alone doesn't save you. B underestimates by an order because it drops Vin−Vout. C follows the basic slope math and lands in the right decade for copper and core loss screening. D describes discontinuous mode, which this load point won't hit.

Q: The SMPS sits in an engine bay, 95% RH, winter salt spray. You're googling "automotive SMPS PCB corrosion under conformal coating". Which degradation mechanism dominates for exposed copper at the inductor terminations?

A: A needs a dissimilar metal couple and an electrolyte path that's not present at the terminations. B matches humidity, bias, and dendrite growth under coating holidays. C would need far higher steady temperatures. D shows up in industrial sulfur environments, not road salt.

Q: Spec references IEC 62368-1:2018, but it's been superseded. Engineering says use the latest. You're searching "IEC 62368 superseded edition contract reference applies". At DFMEA sign-off, what governs?

A: A ignores contract law and change control. B sticks to the invoked edition; anything newer needs an MOC and re-assessed hazards. C confuses test practice with design obligation. D has no standing unless flowed into the contract.
