Linear transformer driver for pulse generation with fifth harmonic
| DWPI Title: Linear transformer driver for generating high current, high voltage square pulses utilized in e.g. Z-pinch inertial fusion energy drivers applications, has fifth-harmonic power delivery module for delivering pulse with frequency to load |
| Abstract: A linear transformer driver includes at least one ferrite ring positioned to accept a load. The linear transformer driver also includes a first, second, and third power delivery module. The first power delivery module sends a first energy in the form of a first pulse to the load. The second power delivery module sends a second energy in the form of a second pulse to the load. The third power delivery module sends a third energy in the form of a third pulse to the load. The linear transformer driver is configured to form a flat-top pulse by the superposition of the first, second, and third pulses. The first, second, and third pulses have different frequencies. |
| Use: Linear transformer driver for generating high current, high voltage square pulses utilized in applications. Uses include but are not limited to high current Z-pinch inertial confinement fusion (ICF) applications, Z-pinch inertial fusion energy (IFE) drivers applications, flash radiography applications and high-power microwaves applications. |
| Advantage: The driver switches the power delivery modules and inductively adds the pulses at low voltage through low inductance transfer and soft iron or ferromagnetic material core isolation, so that the high power pulse is created in the driver. The standard power delivery modules deliver the main sinusoidal pulse into the load, and the MPDMs deliver the pulse that helps flatten a top of the main sinusoidal pulse. The driver provides gas switches to be quiet so as to reduce mechanical shock that can significantly shorten life of an assembly. |
| Novelty: The driver has a core including ferrite rings to accept a load (350) within a center of the ferrite rings. An array of modified power delivery modules (MPDM) (635) delivers pulse (950) with first frequency to the load, where the first frequency is approximately three times of second frequency. A fifth-harmonic power delivery module (FHPDM) (940) delivers another pulse with third frequency to the load, where the third frequency is approximately five times of the first frequency. The core electromagnetically forces the pulses to the load by isolating the pulses from an electrical ground. |
