ENERGY IS USED IN A TREMENDOUS NUMBER OF WAYS.

WE'LL LOOK AT A VARIETY OF DIFFERENT TYPES OF

POWER SUPPLIES. THEIR CONTROLS, HOW THEY OPERATE, AND SOME EXAMPLES OF THEIR APPLICATION.

A POWER SUPPLY COULD BROADLY BE DEFINED TO BE ANYTHING THAT SUPPLIES POWER.

DAMS

SUCH AS

DAMS , AN INTERNAL COMBUSTION ENGINE, OR A HYDRAULIC PUMP.

POWER SUPPLY

FIRST WHAT IS POWERSUPPLY?

B A S I C S

EVERY POWER SUPPLY MUST OBTAIN THE ENERGY IT SUPPLIES TO ITS LOAD, AS WELL AS ANY ENERGY IT CONSUMES WHILE PERFORMING THAT TASK, FROM AN ENERGY SOURCE.

B A S I C S

EVERY POWER SUPPLY MUST OBTAIN THE ENERGY IT SUPPLIES TO ITS LOAD, AS WELL AS ANY ENERGY IT CONSUMES WHILE PERFORMING THAT TASK, FROM AN ENERGY SOURCE.

DEPENDING ON ITS DESIGN, A

POWER SUPPLY MAY OBTAIN ENERGY FROM:

ELECTRICAL ENERGY TRANSMISSION SYSTEMS

BATTERIES AND FUEL CELLS

ELECTROMECHANICAL SYSTEMS, GENERATORS AND ALTERNATORS

SOLAR POWER
