The SSPSM
(
SelfSustained PhaseShifted Mode
)
LCC resonant converter with capacitive output
filter guarantees the ZVS
(
Zero Voltage Switching
)
in whole load range
,
but its analysis and design become
burdensome due to its nonlinearity. The equivalent circuit of SSPSMLCC converter is established
,
which
models the highfrequency transformer
,
secondaryside rectifier and output filter a s the complex impedance
based on the improved FHA
(
First Harmonic Approximation
)
. Its steadystate characteristics are analyzed
,
including
voltage conversion ratio
,
peak resonant current and ZVS features. The influence of key parameters such as
input impedance angle
,
rectifier nonconduction angle and t he resonant capacitor ratio
,
on the steadystate
characteristics is explore d and their design principles are given. A parameter design method for constraining
the input impedance angle is introduced. Experimental results verify the correctness of theoretical analysis
and parameter design.
