Abstract
Described herein are techniques and architectures for gradually transitioning from voltage supplied by a primary power source to voltage supplied by a secondary power source. In particular implementations, a voltage control circuit is used to transition voltage across a load to be supplied by the secondary power source. The voltage control circuit may include a first circuit and a second circuit connected in parallel. The first circuit may include the primary power source connect to the load, while the second circuit may include the secondary power source connected to one or more field-effect transistors. The one or more field-effect transistors may be controlled to cause current of the secondary power source to be gradually transferred to the load. This may result in a transfer of the voltage across the load to be supplied by the secondary power source.
