Don't know the answer? Then you suck!
You cannot use a rectifier to go from DC to AC. You need an oscillator.
Radios use DC power supplies to operate. If a radio is powered from a mains AC supply, a power supply circuit will convert the AC supply to DC. Therefore, a radio may have both a DC and an AC power input but ultimately, the internal circuitry will always use DC.
DC 12V power supply can convert 110/220V AC power source to 12V DC.

because DC generator generates generally generate DC power but as it has slip rings which convert it into ac output power
The easiest way would be to convert the AC power to DC by using a rectifier diode and a filter capacitor. In that way you can now run your DC motor on DC.
You can power your DC toys with the AC power plugs in the house. Like a Radio without using batteries.
A DC/AC power inverter is used to convert DC, the power that comes from a car's battery, into AC, the kind of power that is supplied to a home and used to power larger electronics.
One can convert DC power into AC, one must switch the supplier on and off repeatedly at a fast rate. Once one has done it, the power will be converted.
By using rectification we can convert the AC into DC....

A rotary converter is a mechanical rectifier. A rotery converter is ment to convert AC power to DC power or DC to AC.
