Module Description: This module introduces the fundamental designs of electrical power conversion, both AC to DC and DC to AC, using power electronic circuits. The use of these designs in applications such as renewable energy power supplies ,electric motor drives and lighting controls is also studied.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Explain the principles of operation of half-wave, full-wave, non-controlled and controller rectifier circuits.
LO2 Select a suitable DC-DC convertor to meet the operational requirements of an application.
LO3 Interpret the principles of operation of various inverter circuits.
LO4 Assess an application and employ an appropriate power electronic conversion system.
