how much energy is lost in converting dc energy to ac energy
A rectifier
ac power cant be stored It is much easier to store DC power. Although you might be able to make a case of "stored AC power" - such as the turning mass of a generator - the kinetic energy of this turning mass is converted into AC current - When load suddenly increases, some of this stored kinetic energy is converted into extra electric energy, and the speed the mass is turning at will begin to decay. Before it decays too much (hopefully), the governor on the generator will increase mechanical energy to the spinning mass to keep the speed at the desired value. So in effect a (small?) amount of energy is being stored in the spinning mass, which is then converted to AC power.
mainly AC but can be DC if done correctly
The theory of converting AC to DC using a 3-phase induction motor and a DC shunt generator involves utilizing the induction motor to mechanically drive the shunt generator. When the induction motor is powered by a three-phase AC supply, it operates and drives the rotor of the connected DC shunt generator. This generator then converts the mechanical energy into electrical energy, producing a DC output. The process allows for efficient conversion of AC to DC, leveraging the motor's mechanical properties and the generator's electrical characteristics.
An ac generator produces ac, a dc generator produces dc, it all depends on the generator.
how much energy is lost in converting dc energy to ac energy
this depends on how much energy you are converting, which is why it is so appropriate to talk about this energy loss in terms of efficiency. The energy efficiency of an AC/DC transformer is, also, dependant on the voltage and current that is running through the system, however numbers as low as 75% and as high as 96% would give a reasonable range of efficeincy. To find out how much energy is lost per second (power) just take the Watts of the circuit (volts x amps, simplified) and just multiply that resulting wattage by 1-efficiency, so in the case of the 96% efficient transformer on a 300Watt circuit, the energy loss is 12 watts. These 12 watts get turned into heat, which is why you frequently find that these little transformers for your gadgets are warm.
Of course, when we convert dc to ac, we need to feed an electronic circuit using transformers that have a range efficiency between 80 to 90, depends on the iron composition of the frame.
On average, an AC unit uses about 3,000 to 5,000 watts of energy per hour.
Because, the commutator segments are used for converting AC to DC.
b) a generator. Generators create alternating current (AC) by converting mechanical energy into electrical energy through electromagnetic induction.
A rectifier
Halfwave or fullwave or polyphase AC to DC?
Alternating Current ... like in most households.The adapter is either converting DC to AC or vice versa.
Solar energy is stored in solar panels as direct current (DC) electricity through the photovoltaic effect. This energy can then be stored in batteries or converted to alternating current (AC) electricity for immediate use or to be fed into the grid. When energy is needed, it is released by converting stored electricity back to AC for use in electrical appliances or by using the energy stored in batteries.
The AC is taking energy
A hair dryer is powered by alternating current (AC) electricity. This type of current allows the hair dryer to function effectively by converting electrical energy into heat and air flow.
