No, not every generator produces alternating current. While the majority of generators, especially those used in power distribution, generate AC, there are specialized generators designed to produce direct current (DC). The type of current a generator produces depends on its design, application, and the specific requirements of the end-use.
Re: Constant Current Generator. You will not be able to control the output FET with 5V logic levels since the output of your constant current source output would raise the source voltage and this opposes any switching on/off of the MOSFET. The voltage in constant current mode can rise to up to 10V as you claim.

A constant-current power supply is a power supply circuit that controls the output current to a constant level. Constant-current power supplies are used to power LED lighting and charge rechargeable batteries.

The size and efficiency of a portable generator''s engine determine how much power it can produce. A larger engine with a higher horsepower can generate more electricity, but it also means that the generator will be heavier. Engine efficiency is measured by fuel consumption, usually expressed in gallons per hour (GPH).

2. Shunt Wound Excited Generator. These types of DC generators have field windings that are coupled in parallel with the armature conductor, as shown in the figure. In shunt-wound generators, the voltage across the field is the same as the voltage across the terminal. In this, R sh = Resistance of the shunt winding.
In this way, the current is regulated. As ROUT increases, the voltage on the output rises to a point where the Zener diode conducts, and the device transitions from a CC converter to a CV converter. VIN. CC Mode = IOUT =(RINuVFB)/(RFBuRSENSE) CV Mode = VOUT ~VFB+VZ. Buck Power Stage.
A constant current source is a power generator whose internal resistance is very high compared with the load resistance it is giving power to. Because its internal resistance is so high, it can supply a constant current to a load whose resistance value varies, even over a wide range. Thus, a constant current source follows the rules of current
Some of the recent models have the capacity to deliver in either the constant current or constant voltage mode. [ 4] Constant voltage generators provide a constant voltage over time to the brain. The amount of current delivered depends on the resistance offered in the path of the current. This can be determined by Ohm''s law (I =
