Abstract
Memory state switching is applied to a transient-mode inverter exciting three pairs of Helmholtz coils. The inverter, deploying four transistors and three TRIACS, generates nonrepetitive, orthogonal magnetic fields. Power semiconductor states are predetermined through analysis, digitized, and programmed into an EPROM (erasable programmable read-only memory). The EPROM is then cycled to produce the desired results. The system is intended for demagnetizing ferromagnetic materials in random orientation. Results are presented for an inverter producing a magnetizing force of 350 Oe.<>
