A new method of power pulse modulation with internal frequencies of tens of kHz which is also suitable for multikilowatt power levels is applied to a series-resonant converter system for generating synthesized multiphase bipolar waveforms with reversible power flow. The power circuitry of the converter is provided with one single high-frequency resonant link in the direct energy path. Natural current...
In the paper energy transmission system which transmits the energy from lower voltage AC network to higher voltage AC network is presented. The system contains the DC link subsystem. It is proven that step up chopper used in DC link subsystem decreases the inverter reactive power from AC network. The AC/DC/AC subsystem is used with synchronous generator system and in rotor circuit of slip-ring induction...
In this article, the authors present the design and realisation of a DC/AC inverter. The power cell described is reversible and thus enables the handling of highly reactive loads. A state variable feed-back study leads to the large signal mastery of the power cell. The adaptation of the feedback loop for load variations and source voltage variations are also considered. The article concludes with...
