Note 2: Inverter should be designed with the characteristic of lamp. When you are designing
the inverter, the output voltage of the inverter should comply with the following
conditions.
(1). The area under the positive and negative cycles of the waveform of the lamp
current and lamp voltage should be area symmetric(the symmetric ratio should
be larger than 90%).
(2). There should not be any spikes in the waveform.
(3). The waveform should be sine wave as possible.
(4). Lamp current should not exceed the maximum value within the operating
temperature (It is prohibited to over the maximum lamp current even if operated
in the non-guaranteed temperature). When lamp current over the maximum value
for a long time, it may cause fire. Therefore, it is recommend that the inverter
should have the current limit circuit.
Note 3: Lamp frequency may produce interference with horizontal synchronous frequency and
this may cause line flow on the display. Therefore lamp frequency shall be detached
from the horizontal synchronous frequency and its harmonics as far as possible in
order to avoid interference. In case using the inverter by PWM control, PWM
frequency may interference with frame frequency. We suggest that PWM frequency
is same as frame frequency.
Note 4: Brightness to be decrease to the 50% of the initial value.
