Okay, I mainly work on radar systems and antenna range automation but I'll take a stab.
Floating ground: first picture, see how the ground is there on the right side (after the amplifier) but not on the left? On the left, the battery has a floating ground. It's not directly connected to earth but the battery still provides the same voltage (e.g. 6V). The negative terminal may not be exactly 0V, but that doesn't necessarily matter since the voltage differential into the amplifier will always be 6V.
Half wave rectifier (picture 2): You have AC but you want DC so you cut off the negative portion of the AC curve to give a pulsated DC signal. Controlling the duty cycle (time pulse is off vs time pulse is on) and amplitude of the signal will yield you different average voltage values and therefore different DC values.
Full wave rectifier (pic 3): Like a half wave but uses diodes to make every pulse positive. This gives you twice the range of the half wave (e.g. you can set the voltage to anywhere inbetween 12v to -12v instead of 6v to -6v with a half wave). Of course, the current applied will be halved since you're increasing the voltage by a factor of two. I've never converted a bike to 12v, so I wasn't going to chime in. But if you put on the 12 volt coil and replace the (I assume half wave) rectifier with a full wave you should be good to go.
To El Pollo, I never said that the way to do it wouldn't involve using rectifiers, I said the way you type makes whatever you're trying to say extremely confusing for most.
