Figure 3. Summary of Key Waveforms for I2SF Topology
The key waveforms are illustrated in Figure 3. For the first
phase of the two-switch forward converter, the operation can
be simplified into three modes:
reversed input voltage to the transformer winding to reset
the transformer, while the secondary side is freewheeling
(SFW2 is on).
?
Energy transfer stage (t 0 to t 1 ): Both primary-side switches
(QA1, QB1) and the secondary-side rectifier switch (QR1)
are turned on and energy is transferred from input to
output
?
Dead time stage (t 2 to t 3 ): When the transformer is com-
pletely reset, the converter goes to the dead time stage with
no current in the primary side, while the secondary-side
current continues to freewheel.
?
Transformer reset stage (t 1 to t 2 ): In this stage, two
primary-side diodes (or body diodes) conduct and apply
The second phase operates in a similar pattern but with a 180°
phase shift in the PWMs.
