Note2: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.
