Description
Power electronics is an enabling technology which manages and converts electric power from one form and level to another. Applications of power electronics are vast such as motor drives, renewable electrical energy systems, battery chargers, energy storage systems, data and communication centres, uninterruptible power supplies (UPS) and HVDC. The objectives of this studio are to enable students to apply the nature of power semiconductor devices and their control and use in switch-mode power supply; evaluate the arrangement and topology of the circuits in which switch-mode devices are used; analyse the use of power electronic circuits in high-power applications such as motor drives and power systems; be aware of the electromagnetic interference problems associated with power electronic systems; use commercial software for the rigorous circuit analysis of real power electronic systems; analyse and design circuits to meet certain specifications and standards; and develop basic power electronic circuits and apply them for motor drive applications.

Course intended learning outcomes (CILOs)
This subject also contributes specifically to the development of the following Course Intended Learning Outcomes (CILOs):
- Socially Responsible: FEIT graduates identify, engage, interpret and analyse stakeholder needs and cultural perspectives, establish priorities and goals, and identify constraints, uncertainties and risks (social, ethical, cultural, legislative, environmental, economics etc.) to define the system requirements. (B.1)
- Design Oriented: FEIT graduates apply problem solving, design and decision-making methodologies to develop components, systems and processes to meet specified requirements. (C.1)
- Technically Proficient: FEIT graduates apply abstraction, mathematics and discipline fundamentals, software, tools and techniques to evaluate, implement and operate systems. (D.1)
- Collaborative and Communicative: FEIT graduates work as an effective member or leader of diverse teams, communicating effectively and operating within cross-disciplinary and cross-cultural contexts in the workplace. (E.1)
- Reflective: FEIT graduates critically self-review their performance to improve themselves, their teams, and the broader community and society. (F.1)

Teaching and learning strategies
This is a studio-based subject that aims to achieve specific learning goals via studio and laboratory sessions that eventually lead to an open-ended project development. Students acquire basic power electronic knowledge, based on their background and pace of learning, through a series of online videos, online quizzes, and tutorials. Students will form teams to design and develop an application of power electronics and drives of their own choice. Teams are aided and guided by tutors who are knowledgeable and experienced in the design, development and testing of power electronic systems and provide dialogic feedback during labs and tutorials.
Students are expected to attend studio sessions to access opportunities to strengthen their knowledge in power electronics and drives through inquiry. These tutorial-style sessions are designed as building blocks of learning where tutors provide weekly feedback on student progress, intended objectives of activities and support of achievements. Assessment tasks are be further informed by these regular interactions. Formal assessment of the project outcomes and deliverables occurs at mid-session and end of session.
