High V AC, high temperature (wound)
Operation at overvoltages during heating and ignition of lamps (T A ≤ 40 ° C)
In lighting applications, the capacitors can be subjected to overvoltages during the heating and ig-
nition periods. An overvoltage occurs when the operation voltage exceeds the permissible
AC voltage at the resonant frequency f r .
For a repetitive application of on/off switching pulses (as for example in the life tests applied by
electronic ballast manufacturers), limits have to be imposed on the time periods under overvolt-
age and on the duty cycle, in order to keep the capacitance value within the required margins:
The overvoltage time t OV should be less than 1 sec.
The maximum duty cycle of the overvoltage is given by
where V RMS,ov is the RMS voltage during period t OV
and V RMS is the permissible AC voltage for continuous operation at the resonant frequency f r
(given by the “permissible AC voltage versus frequency f” graphics in theprevious pages).
The drift of capacitance depends on the V pp attained, and the total time under overvoltage,
which is calculated in hours as follows:
(N i
t OV ) / 3600
where N i is the number of overvoltage impulses and t OV is expressed in seconds.
The maximum drift of capacitance as a function of both parameters is provided graphically in the
following pages.
