Uninterruptable Power Supply systems (UPS) form an integral part for most of the applications that require a stable and reliable power supply. Loss of electrical power to critical equipment may lead to equipment damage, extensive repairs and/or unnecessary disconnection (shutdown) of vital equipment such as: computers, servers, process control equipment, etc.
Indirectly this could lead to production losses and loss of revenue. Power outages should not be our only concerns, management and electrical engineers should also be nervous about the quality of the power supply (the presence of surges/spikes, dips, harmonics, etc.) when it comes to supplying power to critical applications. For this workshop the participants require a working knowledge of basic electrical engineering principles. Essential aspects of the key power electronic components to be found in UPS systems will be revised at the beginning of the workshop. This two day technical workshop kicks off with a discussion on the need for UPS systems; we’ll refresh our memories on power electronic components and the conversion of electrical energy from DC to AC, after which we’ll compare the different UPS topologies and their modes of operation, continuing with typical applications.
We’ll discuss the main components found within a typical UPS and how AC is converted into DC and then inverted back to AC.
