Power Electronics is the study of switching electronic devices and circuits to convert and control the flow of electrical energy. Power Electronics is the basic technology of switching power supplies, power converters, power inverters, motor drives, and motor soft starters. Inverters are devices that transform DC input into fixed AC output through changing the trigger angle, in the ideal statues the output wave form is perfect sine wave, however in the practical case it has some higher harmonics that need to be reduced. Inverters are an important part of UPS systems, fully explained in this chapter, where UPSs are uninterruptible Power Supply in which the inverters are included as an essential part, that can provide emergency power to a load when the input power source or main power source fails.

Buildings maintenance has received increasing international attention in various fields of scientific research. As a result, the maintenance of buildings has changed from the preventive to the predictive approach. This is done through an evaluation model to support and assist the management of the facility in selecting alternatives and making appropriate decisions in maintenance according to building status and maintenance budget. This chapter investigated the reasons for the electrical maintenance of the university buildings and the degree of importance of each element of electrical maintenance through the design of a questionnaire in which the electrical components were divided into elements and then each element was linked to all maintenance items that related to it. At the end of the research, mathematical models were developed, and they help to forecast the electrical maintenance items and distribution of the maintenance budget, and to verify the validity of these models. The models have been applied to study the case of dorm buildings in Tishreen University.

With the development of smart grid technology, residents can schedule their power consumption pattern in their home to minimize electricity expense, reducing peak-to-average ratio (PAR) and peak load demand. The two-way flow of information between electric utilities and consumers in smart grid opened new areas of applications. In this chapter, the general architectures of the home energy management systems (HEMS) are introduced in a home area network (HAN) based on the smart grid scenario. Efficient scheduling methods for home power usage are discussed. The energy management controller (EMC) receives the demand response (DR) information indicating the Time-of use electricity price (TOUP) through the home gateway (HG). With the DR signal, the EMC achieves an optimal power scheduling scheme that can be delivered to each electric appliance by the HG.
