for controlling a motor if it is in a important application we use rectifiers because the ripple factor of the chopper is very high in comparison with choppers
Chemical Processes often have large power rectifiers as their primary source of DC Power. If these rectifiers are turned off, either for maintenance or a malfunction, there is a danger to the hardware of the chemical process. To solve this problem, standby rectifiers are installed in parallel with the main rectifiers. These rectifiers, known as Polarisation Rectifiers, pass electric current through the process and prevent damage....NEOWATT ENERGY
chopper
The advantage of chopper amplifiers is that they help to amplify really low signals with high gains. This is commonly useful for electronic instrumentation.
A chopper to chop DC into AC is an electronic switching. Digital is data bits or machine language whereby a processor can make decisions
chopper use a ststeing perpose..... dc means direct current that is low voltage
the differecne is that overload means to much overuse means that you use it to much.
There is no difference, "chopper" is slang for 'helicopter'
CHOPPER is only a slang word of HELICOPTOR...
hi, i wanted to konw the differecne beteen money and cerdit so if case there is the answer let me konw
The purpose of rectifiers is to change AC to DC.
Precision rectifiers are used in the design of instrumentation systems.
Maplin offer affordable rectifiers. Rectifiers are used to convert alternating current to direct current. The process is also known as rectification. Rectifiers are often found serving as components of DC power supplies.

Single phase rectifiers are suitable to power loads of up to only about 15 kW. For higher power demands, three phase rectifiers are preferred for the following reasons: Higher dc voltage, better TUF, better input power factor, less ripple content in the output current - therefore giving better load performance and a smaller size of filter circuit parameters because of the higher ripple frequency.
Jones chopper is known as voltage commutated chopper...it is one type of chopper..
