  • Mitigation of voltage collapse through active dynamic buffers

    Power electronics continues to grow as an element of electrical loads. Most such loads, including motor drives, computer power supplies, and compact fluorescent lighting, serve to 'isolate' the load dynamics from the utility grid. The unfortunate effect is that these loads enforce local constant power behaviour. This tends to destabilise the supply system, resulting in voltage collapse. In this ...
