-The paper comes up with a full-package solution to convert solar power
into AC.This solution is based on the design of the full-bridge converter
and the full-bridge inverter.This paper first gives full analysis on the
theories of power switching technology,inverter technology and PWM
technology.And the theory and fulfillment of PID algorithm are
discussed in this paper.Especially for this solution,this paper comes up
with a PID algorithm in which two variables are being controlled in one
close-loop.
Then,this paper gives the procedure to calculate the main circuit
parameters.The design of digital controlling circuit and assistant circuits,
such as MOSFET driving circuit and voltage protection circuit,are
introduced.Based on the parameters worked out,the paper gives the
simulation of whole system in Matlab/Simulink.This paper also
introduces the firmware design based on the DSP(TMS320F2812).
The last is the verification of whole system including hardware and

Description: systematic method for deriving three-port
converters (TPCs) from the full-bridge converter (FBC) is
proposed in this paper, which splits the two switching legs of the
FBC into two switching cells with different sources and allows a
DC bias current in the transformer. By using this systematic
method, a novel full-bridge three-port converter (FB-TPC) is
developed for renewable power system applications with merits of
simple topologies and control, reduced number of devices and
single stage power conversion between any Platform: |
