An adaptive delay control method for a phase-shifted full bridge converter with a synchronous rectifier is presented. With this control, the delay time between primary and secondary switches can be optimised to reduce dead time, according to output power. Moreover, due to the poor third quadrant conduction of gallium nitride (GaN) high-electron-mobility transistors (HEMTs), the dead time needs to...
In this paper, a novel new pulse power generator based on IGBT stacks is proposed for pulse power application which can be used for PSII applications. Because it can generate high voltage pulse output without any step-up transformer or pulse forming network, it has advantages of fast rising time, easiness of pulse width variation, high repetition rate and rectangular pulse shape. Proposed scheme consists...
In this paper, a novel new pulse power generator based on IGBT stacks is proposed for pulse power application. The proposed scheme consists of series connected 9 power stages to generate maximum 60 kV output pulse and one series resonant power inverter to charge DC capacitor voltage. Each power stage is configured as 8 series connected power cells and each power cell generates up to 850 V DC pulse...
