Redundant power supply concepts
... For example, a controller that requires 5 A is supplied by two redundant power supply units, each with a rated current of 5 A. The user now connects an additional load drawing 3 A. Due to its power reserve, the power supply easily provides 8 A without resulting in any voltage dip. However, the syste ...

Implementation of Thyristor Switched Capacitors for Power Factor
... They will supply or sink reactive power regardless of whether there is a corresponding load operating nearby, increasing the system's no-load losses. In a worst case, reactive elements can interact with the system and with each other to create resonant conditions, resulting in system instability and ...
