INTRODUCTION
Power electronics covers power conversion and energy management aspects in electronic products and systems. It is an enabling technology for electronics.

PAPER DESCRIPTION

This 15 point paper covers the theory, design, applications and the systems approach in power electronics. Subjects include: power semiconductors, linear and switching power supplies (DC-DC converters), rechargeable batteries and management, DC power management, AC power conditioning and surge protection, energy storage devices, digital control in power electronics, and power integrated circuits.

PAPER STRUCTURE

The paper consists of lectures, tutorials and laboratories including design and construction projects. Details of lectures, lab content and the projects are provided in the attached teaching plan. Please note that the laboratories start in the second week of the semester and are an ESSENTIAL part of the course.

How you will be assessed

Edit How you will be assessed Content

Details on the course assessment – including due dates – are provided in the introductory sections of both the laboratory manual and study guide. This includes instructions regarding length, structure, presentation, and style, and referencing format for the essay assignment. The dates indicated for assessment procedures will normally be adhered to. Any changes in the dates will be made in consultation with the class, at least one week prior to the original date.

Course work: final assessment ratio is 50:50.

Internal assessment (50% of final mark): one test on lecture content, worth 10%; Lectorails will also be assessed through four assignments.

Test will be conducted during the during the tutorial hour on Friday 22 nd Sept. The assignments will be equally weighted and make up 20% of the course grade.

Labs (including design and development project components) make up 20% of the course grade. At least 70% of labs must be handed in for marking.

External assessment: final assessment (50%) will be a supervised event held during the examination period of the semester. This will be one to three hour event. Format will be informed later, based on the current Covid-19 related guidelines from the university management. A minimum mark of 40% is required in the final assessment in order to receive a passing grade.

This paper facilitates the development of technical writing, an important competency expected of a scientist and engineer. In order to pass this paper, students are expected to demonstrate their ability to produce written work of an adequate standard.

Samples of your work may be required as part of the Engineering New Zealand accreditation process for BE(Hons) degrees. Any samples taken will have the student name and ID redacted. If you do not want samples of your work collected then please email the engineering administrator, Natalie Shaw (natalie.shaw@waikato.ac.nz), to opt out.

Edit How you will be assessed Content

The internal assessment/exam ratio (as stated in the University Calendar) is 50:50. There is no final exam. The final exam makes up 50% of the overall mark.

The internal assessment/exam ratio (as stated in the University Calendar) is 50:50 or 0:0, whichever is more favourable for the student. The final exam makes up either 50% or 0% of the overall mark.
