7) Impulse voltage waveform parameter(with load capacitance:300~3000pF):
     a) Standard lightning impulse voltage full-wave: 1.2±30%us /50±20%mus, Oscillation at peak value less than 3% of amplitude
     b) This two impulse voltage waveform parameter and deviation meet the requirement of GB311.1 and GB16927.1 national standard.
8) Minimum output voltage efficiency
    Standard lightning impulse voltage full-wave≥90% (with load capacitance less than 1000PF)
9) Synchronous range: stage voltage is between 20%~100% of rated voltage.
    Positive and negative polarity synchronous range: bigger than 25%.
10) Synchronous discharge out of control rate <5%
11) Minimum output voltage:≥±10% rated voltage
12) Charging voltage instability <±1.0%
13) Working time:
       When voltage above than 2/3rated voltage, the systems can continuous working each 120s (charging and discharging).
       When the voltage is below 2/3 of rated voltage, the system the system can continuous working (charging and discharging).
