This is not a perpetual motion proposal, on the contrary, is a machine that wears out of parts and has energy loses but like a car, it can be highly effecient due to a scheduled service plan.

An alternator which has a hand lever to jump start it. The electric power generated by the alternator powers an electric motor which has a VSD (variable speed drive) connected to it. The machanical power generated by the motor is then delivered back to the alternator via a manual gearbox. 

Imagine, a bicycle. Replace the paddles with a motor which has a VSD, and the back wheel with a generator with gears on it. At first, the motor drives the alternator with with a small gear at a normal speed/frequency. Then gradually increase the gear until you reach the largest gear at the same time increasing the speed/frequency of the motor. Gears=power. Frequency/speed=torque.

Will it produce surplus power?

Short answer: no. There will be losses in the described setup and no surplus power. As far as I can tell the proposed device is a typical attempt at constructing a perpetual motion device, something that is not possible.

An engine that convert mechanical energy into electromagnetic energy cannot operate with 100% efficiency because it is impossible to design any system that is free of energy dissipation. For further reading the wikipedia article on perpetual motion may be a good start: https://en.wikipedia.org/wiki/Perpetual_motion

The error is in thinking that different gears produce different power. They don't. They produce different torque at different (angular) speeds. Power is torque x speed. If you start with one gear and then switch to another with double the speed, it delivers only half the torque. So the power transmitted is unchanged.
