Power electronics and Electronics - What is the differences ?
Answer:
As chipdeutsch says, the difference is the voltage and current or the total power handled by the electronic equipment. I don't believe that there is a specific dividing line such as 30 V and 1 A, but that is a reasonable guideline.
Power electronics is generally concerned with the generation, transmission and control of power rather than communication, but the design of high power radio and television transmitters is more a power electronics field. The low power instruments used to monitor and control electric power generation and transmission may or may not be considered power electronic devices.
Electronic equipment is used to control motors ranging from the disc drive motors in a computer to large motors rated above 500,000 horsepower (375 kW). The design of the power handling circuits in that type equipment is done by power electronics designers, while the control circuits are designed by electronics engineers and embedded processor engineers and programmers.
I guess power electronics is more towards power/energy systems...
For an electronic, everything above 30V and 1 A (that is 30 watts) is "high power"... but there are electronic circuits that work above those levels, and can handle as many kilovolts and hundreds of amps as you need... but for normal electronics, you are always on the "low side" of the power... we are very efficient
