This paper presents a phase angle control method of coil currents in a zone-control induction heating (ZCIH) system, which has split working coils on a work piece. The ZCIH system controls the amplitude of each coil current to make the temperature distribution on the work piece uniform. The coil currents should be adjusted to be in phase with each other to control the current amplitude in a wide range...
A special round robin (RR) algorithm has been developed to equalize nickel metal hydride (NiMH) battery packs using a new selective equalizer. This algorithm detects batteries either at a very low state of charge (SOC) or at an extremely high SOC. In this system, a set of electromechanical relays are connected in a matrix to route boost current to the weaker batteries. The relay switching is controlled...
The magnetooptic recording characteristics of three types of DyFeCo films with a quadrilayer structure were measured using three recording methods: optical modulation, magnetic field modulation and the laser-off method. In the laser-off method, the laser power was lowered only while the magnetic field was changing. The transition metal (TM)-rich medium had the best carrier-to-noise (C/N) ratio when...
