These mains applications are strictly regulated in safety standards and therefore electromagnetic interference suppression capacitors conforming the standards must be used. To select the capacitor for a certain application, the following conditions must be checked: 1. The peak voltage (UP+) shall not be greater than the rated DC voltage (UNdc) 2. The peak-to-peak ripple voltage (UP-P) shall not be greater than 0.1 x (UNdc) Non reversing recurrent waveform 3. The voltage peak slope (dU/dt) shall not exceed the pulse slope at the DC voltage rating. If the pulse voltage is lower than the rated DC voltage, the rated voltage pulse slope may be multiplied by UNdc and divided by the applied voltage. For all other pulses following equation must be fulfilled: T is the pulse duration 4. The maximum component surface temperature rise must be lower than 15 °C. MAXIMUM REPETITIVE PEAK VOLTAGES The capacitor unit may be subjected to the following surge without any significant reduction of lifetime expectancy REPETITIVE SURGE VOLTAGE MAXIMUM DURATION PER DAY 1.1 x UNdc 30 % on load duration 1.15 x UNdc 30 min 1.2 x UNdc 5 min 1.3 x UNdc 1 min 1.5 x UNdc 110 ms U p+ UNdc U p- t 2 dU dt -------- ⎝⎠ ⎛⎞ 2 0 T ∫ dt U Ndc dU dt -------- ⎝⎠ ⎛⎞ rated × < × × |
