Opis:: The paper describes novel power generation topology wherein synchronous generator have a parallel connected power electronic converter. In this arrangement synchronous generator is only source of active power and power electronic converter is source of reactive power. Such power distribution allows to increase the synchronous generator generated active power by 25%, and operate with unity power factor. The power converter with energy storage system embedded can deliver additional active power in transient state to improve generator stability.

Opis:: Paper presents hybrid on-line UPS system (H-UPS). Presented system is based on a on-line (double conversion) UPS. H-UPS consists of two controlled energy storage systems. The first one is a static energy storage system based on supercapacitor bank. The second energy source is adjustable speed generating system supplying DC link voltage. A control concept of the UPS operation, according short and long failure of the supply utility voltage is developed. The 5 kW H-UPS is designed, built and tested. The control unit is built using DS P processor based on Shark from Analog Devices. The design and system stability tuning is achieved using PSIM software. Laboratory tests confirm high quality of the produced AC voltage during transients (voltage failure) and during steady state operation without external supply voltage.
