Through this work, the methods of obtaining a pillar voltage are discussed in various ways. Particularly discussed is the way to obtain a pillar voltage using a Bootstrap generator as one of the most widely used generators. The described way of generating the pillar voltage is realized with practically discrete elements. In addition to the practical realization of the device, a rectangular pulse generator is made, which triggers the pillar voltage generator. For this purpose, an astable multivibrator, a monostable multivibrator and a Schmitt's trigger circuit are practically realized in order for the rectangular pulses to be arranged. The realization of the pillar voltage generator is performed according to the task so that the frequency can be changed from 10 Hz to 10 kHz and the output voltage amplitude up to 20 V. The pillar voltage generator device is designed to have autonomous triggering, and there is also the possibility of an external trigger. For this purpose, stabilized power supplie of -9 V and + 24V are made in discrete technology.
