The paper presents the design and implementation of a soft-switching invert
er with zero voltage transition (ZVT) for shaker armature excitation. First
, the circuit configuration and the operation principle of the proposed inv
erter are introduced in detail. A quantitative design procedure is develope
d according to the governed equations derived in various operation modes fo
r finding the values of soft-switching circuit components. Then the impleme
ntation of the switching control circuit for the successful operation of th
e proposed soft-switching scheme is described. Finally, the performance of
the shaker table fed by the designed soft-switching high frequency inverter
is demonstrated by some simulation and measured results. The results show
that less switching loss and switching stress of the inverter switch are ob
tained by the proposed soft-switching scheme.
