Original Abstract
This paper presents a high-amperage current pulse generator with a high-voltage internal power supply. The generator was designed and constructed specifically for upcoming magnetic therapy experiments on cancerous tissues and can deliver currents up to +-100A. The high-voltage power supply will be needed to achieve fast current changes in the large application coils. Due to the high required currents, the generator uses a relatively simple switching mode approach and employs full bridge of power IGBT transistor as the switches. This has the advantage of very high power efficiency, but the output waveforms are limited to short current spikes only.

Článek popisuje výkonový proudový pulsní generátor s interním zdrojem vysokého napětí. Tento generátor byl navržen a sestrojen pro experimentální magnetoterapii na rakovinových buňkách a dokáže dodat proudy až do +-100 A. Vysokonapěťový zdroj je nutný k dosažení rychlých změn proudu ve velkých aplikačních cívkách. Vzhledem k vysokým požadovaným hodnotám proudu byla použita spínaná topologie, přičemž v generátoru je plný most z IGBT tranzistorů. Díky tomu má generátor dobrou účinnost, ale výstupní průběhy jsou omezeny jen na krátké jehlové pulsy.
