Battery-charger demands have changed from a simple stand-alone charger to an embedded charger and power source for the system. This topic provides some insight into the many new issues the designer should consider when designing either a linear or a switching regulator. Common transient issues caused by hot plugging/unplugging the adapter or system load during operation are presented. Problems ...

WINSmartEV is a software based plug-in electric vehicle (PEV) monitoring, control, and management system. It not only incorporates intelligence at every level so that charge scheduling can avoid grid bottlenecks, but it also multiplies the number of PEVs that can be plugged into a single circuit. This paper proposes, designs, and executes many upgrades to WINSmartEV. These upgrades include new ...

The self-oscillating flyback converter is a popular circuit for cost-sensitive applications due to its simplicity and low component count. It is widely employed in mobile phone chargers and as the stand-by power source in off-line power supplies for data-processing equipment. However, the optimization of this circuit is almost exclusively performed by a cutand-try approach since its operation i...

A foundational property of bidirectional transformations is that they should be correct: that is, the transformation should succeed in restoring consistency between any models it is given. In practice, however, transformation engines sometimes fail to restore consistency, e.g. because there is no consistent model to return, or because the tool is unable to select a best model to return from amo...

Quantum battery works as a micro- or nanodevice to store and redistribute energy at the quantum level. Here we propose spin-charger protocol, in which cells are charged by finite number of spins through general Heisenberg $XY$ interaction. Under isotropic interaction, protocol is endowed with higher capacity terms maximum stored than conventional protocols, where continuous-variable system, e.g...
