2.2.1.
Input
Transformer
This
transformer
is
manufactured
as
H
class
dry
type.
The
output
voltage
is
designed
to
correspond
the
input
voltage
of
inverter
and
charging
voltage
of
battery,
and
the
output
current,
to
sufficiently
match
the
sum
of
the
charging
current
and
the
rated
current
of
inverter.
2.2.2.
Rectifier
&
Battery
Charger
This
unit
includes
the
thyristor
module,
heat
dissipation
board,
and
many
other
components.
It
will
convert
input
AC
power
to
DC
power,
supply
the
inverter,
and
simultaneously
charge
the
battery
with
the
best
condition
possible.
Also,
the
filtering
circuit
composed
of
reactor
and
condenser,
is
employed
to
filter
out
the
ripple
characteristics
contained
in
the
rectified
DC
power,
in
order
to
yield
the
best
possible
DC
power.
2.2.3.
Inverter
This
unit
contains
IGBT
(Insulated
Gate
Bipolar
Transistor)
module,
heat
dissipation
board,
rapid
firing
fuse
for
the
semi-conductor
protection
and
other
relevant
component.
The
high
frequency
switching
and
the
sine
wave
Pulse
Width
Modulation, are
utilized
in
this
unit.
The
inverter
will
revert
the
DC
power
obtained
from
rectifier
to
PWM
AC
output,
and
then
the
AC
filter
will
make
it
very
similar
to
the
balanced
sinewave
AC
voltage
to
supply
the
critical
load.
