This paper presents an experimental switched-reluctance generator (SRG) based distributed power system with common DC grid and single-phase AC 220/110V 60Hz outputs. First, a SRG with suitably designed power converter and control scheme is constructed to generate robust DC 48V output. Then it is boosted to establish a 400V common DC grid by a current-fed push-pull (CFPP) DC/DC converter. Well-regulated...
A singular perturbation technique for modelling and simulation of a class-E DC-DC converter with piezoelectric transformer (PT) is presented. The open-loop characteristics of this converter are analysed. The singular perturbation method and the generalised state-space method are compared to model this DC-DC converter. In addition, a precise model which is based on the exact equations is used as a...
The class-E DC-DC power converter using piezoelectric transformer as the voltage stepping is examined in this paper. A generalized state-space averaging method is used for modeling. The system is simulated to examine the models. The open-loop characteristics of this converter are analyzed based on this model. In addition to simplifying this model, the singular perturbation method is used. In the end,...
The DC power converters have reactive components for steady state and transient energy storage. The energy stored in similar to the reactive components in AC system which uses a power factor defines how the energy is handled. A DC energy factor is introduced in this paper that is particular to address this issue. The set of formulation is developed to get understanding the DC energy storage and the...
This paper examines the H-bridge converter using passivity based control. The nonlinearity of resonant type H-bridge converter is poor and therefore the dynamic performance of the converter is weak. Using simple PI control, the transient response is not satisfactory. The passivity based control is first derived for the H-bridge converter. The parameter estimation is examined and the comparison with...
