operation of the FBR, during each half
current cycle, it takes a while for IS
to invert the voltage across CP
so as
to turn on the alternating paths in
the rectifier, as shown in Figure 2(c).
This duration can be dramatically
decreased with the use of a synchronized
switched inductor, as shown in
Figure 5(a) and (b). With a constant
VRECT
at the quasi-steady state, this effectively
regulates the voltage amplitude
across
C .P
As IS

does not need to
the transducer
in P-SSHI sees only the effective loading
through the rectifier, bypassing CP
entirely. As a result, the short-circuit
type of operation is optimized at L1
and C s1
\ resonant frequency, ~SC .
With IS that flows to VRECT
through
the rectifier, we can calculate the extracted
energy per cycle as
2QV .

Compared to the case with SECE, which
is

VOC is replaced by V .RECT
cance of this simple replacement is
that this allows MPT by tuning VRECT

In real implementations, the voltage
inversion incurs loss in the switches.
As a result, after each voltage inversion,
a portion of IS
charge CP before the rectifier can be
turned on, degrading the extracted
power. To improve the voltage inverIS

process, large inductors on the
order of several millihenries are often
adopted to reduce the inversion current
and associated loss. Javvaji et al.
[26] proposed a multistep P-SSHI design
that allows the use of a smaller
inductor as shown in Figure 5(c) and
(d). With a 47-μH inductor, the proposed
five-step design improves the
inversion efficiency from 73% to close
to 90%.
In P-SSHI, as VRECT affects the exstill

tracted power and needs to be set properly,
the energy storage capacitor needs
to be placed somewhere else, and a connecting
module is needed in between.
A common practice is to adopt a
switching type of dc-dc converter that
