Semiconductor converters- Electrical test methods
1 Scope
This standard specifies general electrical test methods for semiconductor
converters.
This standard applies to various ordinary converters, including rectifiers,
inverters, converters with both rectification and inverter operation modes,
various power electronic switches. The dedicated converter can also use it as
a reference.
This standard does not apply to converters for motor vehicles and onboard
converters for aviation electrical appliances.

the dated documents, only the versions with the dates indicated are applicable
to this document; for the undated documents, only the latest version (including

4 General requirements for test
4.1 Overview
This standard gives general electrical test methods for semiconductor
converters, see Appendix B for test circuits. The division of specific electrical
test methods and test types not given in this standard shall be specified in the
product standard.
The results of all tests shall be determined in accordance with the provisions of
the product standards.
Measuring position:
- Between circuits that are not electrically connected to each other;
- Between the circuit and the case.
The insulation resistance is only used as a reference for the insulation voltage
test, not as an assessment.
5.1.2 Insulation voltage test
Under normal circumstances, follow the test in 7.2.2 of GB/T 3859.1-2013.
Converters using water cooling are generally tested without water.
When it is inconvenient to apply an AC test voltage, it may apply a DC test
voltage equal to the peak value of the specified AC test voltage.
The time for the test voltage to rise from zero to its specified value shall not be
less than 10 s, or from 50% of the specified value, each stage is, at 5% of the
specified value, gradually increased to its specified value.
During the exit-factory test, if the test voltage is enough to rise to its specified
value within 1 s, it is not necessary to increase the test voltage step by step.
5.1.3 Ground resistance measurement of accessible metal parts
It can be measured by direct measurement method.
Before measurement, the converter shall be disconnected from the power
supply and load; clean up the contamination (if any) at the specified
measurement point.
When measuring, the terminal of the meter is connected to the ground terminal
and the case, respectively (or conductive metal parts that shall be grounded).
5.1.4 Light load test
Test procedure:
- Adjust the input voltage to reach the rated value (type test shall be
performed at the maximum and minimum rated input voltage);
- Adjust the output voltage to reach the rated value (the load current can meet
the test requirements);
- Check whether the display instrument, trigger device, protection device,
cooling device and fault detection unit can work normally.
in ampere (A);
IM - In each parallel valve device, the average current carried by the device
carrying the largest current share, in ampere (A);
np - The number of parallel valve components.
5.1.7 Rated current test (low-voltage current test)
If it is more convenient, the load test under rated conditions can be used instead
of this test.
Test procedure:
- Connect the input terminal of the converter to a power supply capable of
generating a rated continuous current through a voltage regulator or a low-
voltage converter transformer; the output terminal is directly short-circuited
or short-circuited through a reactor;
- Adjust the voltage through a voltage regulator or phase control (if available)
so that the output current reaches the rated value;
- Check the operation of each part of the converter.
During the test, the control devices (if any) and auxiliary devices are powered
by an independent power supply at a rated voltage.
5.1.8 Load test
Test procedure:
- Adjust the input voltage and load current to reach the rated value;
- For converters with adjustable output, adjust the output voltage to reach the
rated value;
- Check the operation of each part of the converter.
5.1.9 Temperature rise test
The test shall be carried out as far as possible under conditions equivalent to
the specified load. The test can be performed simultaneously with the rated
current test or the load test under rated conditions.
The temperature rise shall be measured under the harshest rated cooling
conditions. If the test is carried out under the temperature lower than the...
