IEC61000-4-4 performance
AC switches have been tested according to IEC61000-4-4 test. This test allows assessment
of the AC switch robustness against electrical fast transients.
Figure 44.
IEC61000-4-4 test with STEVAL-GLA001V1
Measurements were performed under the following conditions:
•
Vmains = 230 Vrms / 50 Hz
•
Tamb = 22 °C
•
STM32 Nucleo board connected and supplied by STEVAL-GLA001V1
•
5 kHz - burst duration = 15 ms and repetitive burst period = 300 ms
•
100 kHz - burst duration = 0.75 ms and repetitive burst period = 300 ms
•
Test duration: 1 minute
1.
Criteria A:
The aim of this test is to withstand 2 kV transient under normal operation (no abnormal behavior
allowed during and after the test). For this criteria, the test is done twice: first with X101 in phase control
mode (to check the normal AC switch operation) and with X102 and X103 OFF (to check that there is no
spurious turn-on); the second time with X103 in phase control mode and with X101 and X102 OFF.
2.
Criteria B:
The aim of this test is to withstand 4 kV transient with normal operation at the end of the test
(operation temporary disturbed allowed if followed by a self-recovery). For this criteria, the test is done twice:
first with X101 in phase control mode (to check the normal AC switch operation) and with X102 and X103
OFF (to check if there is spurious turn-on); the second time with X103 in phase control mode and with X101
and X102 OFF.
