Hello, I want to make voltage converter from accumulator 12V DC to about 150V DC. I' ve seen a few schematics but I cant understand them.
How i can make about 150V DC from 12V DC?

You can use a DC-DC boost converter (1-transistor boost converter).

You can also use a push-pull converter.

I recommend using the push-pull converter, as, when the switches are off, output is zero, whereas in the boost converter when the switch is off, VOUT = VIN. And the output is isolated from the input as well.

For push-pull converter, take a look here:

Hope this helps.

The above shown diagram (in post #4) is like a flyback converter.

An RCD snubber should be used across the transformer primary. Another snubber could be used across the MOSFET (to reduce the rate-of-rise). At the secondary, a single diode followed by an LC filter should be used to convert to DC (the inductor may be omitted) - not a bridge rectifier.

Hope this helps.
