MODULE
voltage with the active module, to create a DC voltage.
(1) Active module
The active filter, consisting of a reactor and switching
element, eliminates higher harmonic components
contained in the current generated when the
compressor is operated, and improves the power-
factor.
(2) Diode stacks
These rectify the 220-240 V AC from terminals A and
B to a DC power supply.
<Reference>
@ Incase of malfunction or defective connection:
immediately after the compressor starts, it may
stop due to "abnormally low speed" active error,
etc.
The compressor may continue to operate
normally, but the power-factor will decrease, the
operation current will increase, and the overcurrent
breaker of the household power board will probably
activate.
@ Incase of active module faulty or defective
contact:
Although the compressor continues to operate
normally, the power-factor will decrease, the
operation current will increase, and the overcurrent
breaker of the household power board will probably
activate.
<Reference>
@ If diode bridge 1 is faulty, the compressor may
stop due to "Ip", "abnormally low speed", etc.
immediately after it starts, or it may not operate at
all because no DC voltage is generated between
the positive 4 and negative terminals.
If diode bridge 1 is faulty, be aware that the 25A
fuse might also have blown.
@ If diode bridge 2 is faulty, DC voltage may be not
generated and the compressor may not operate at
all. Also, be aware that the 3A fuse might have
blown.
