Metastability of Pulse Power Loads with Nonlinear Coupled Magnetics

Pulse power loads are becoming increasingly more common in many applications primarily due to applications like radar, lasers, and the technologies such as EMALS (Electro-Magnetic Aircraft Launch Systems) on next-generation aircraft carriers. Pulse power loads are notorious for causing stability issues. Stability for pulse power loads can be defined as metastable, where the system can be unstable for a portion of the pulse as long as the stability is re-established over the entire pulse. Dynamic characteristics for step changes in load can be improved with a modified boost converter topology in conjunction with bang-bang control. Improvement in the metastability margins will be presented through simulations with the application of the modified topology to pulse power loads.
