Title: IEC 61000-4-13:2019: A Technical Article on Electromagnetic Compatibility and Its Importance

Electromagnetic compatibility (EMC) is a crucial aspect of the development and use of electronic devices and systems. IEC 61000-4-13:2019, also known as "Electromagnetic compatibility - Part 4-13: Testing and measurement techniques - Harmonics and interharmonics including mains signalling at a.c. power port, low frequency immunity tests," is an essential international standard that defines a set of conditions for simulating realistic electromagnetic environments. In this article, we will discuss the purpose and testing process of IEC 61000-4-13:2019 in greater detail.

Purpose of IEC 61000-4-13:2019:

The primary purpose of IEC 61000-4-13:2019 is to define a set of conditions that simulate realistic electromagnetic environments. By subjecting electrical and electronic equipment to these tests, manufacturers can assess the performance and susceptibility of their products to electromagnetic interference from radio transmitters or other sources. The standard aims to ensure that products are capable of operating without being affected by electromagnetic interference from these sources.

The Testing Process:

IEC 61000-4-13:2019 provides guidelines for conducting the tests, test levels, and evaluation criteria to ensure that devices can function properly in the presence of electromagnetic interference. The standard defines four different test procedures, which are designed to simulate different types of electromagnetic environments.

The first test procedure is called "IEC 61000-4-13:2019-1," also known as "Class B," which is designed to simulate low-frequency electromagnetic interference (EMI) from radio transmitters. This test procedure involves the use of a signal generator and a signal receiver to generate a test signal at a frequency of 1 kHz and 5 kHz, respectively. The generator is connected to a power port, and the receiver is connected to a ground port. The test equipment is designed to measure the immunity of the equipment to EMI from the test signal.

The second test procedure is called "IEC 61000-4-13:2019-2," also known as "Class A," which is designed to simulate high-frequency electromagnetic interference (EMI) from radio transmitters. This test procedure involves the use of a signal generator and a signal receiver to generate a test signal at a frequency of 1 MHz and 5 MHz, respectively. The generator is connected to a power port, and the receiver is connected to a ground port. The test equipment is designed to measure the immunity of the equipment to EMI from the test signal.

The third test procedure is called "IEC 61000-4-13:2019-3," also known as "Class C," which is designed to simulate immunity from both low-frequency and high-frequency EMI from radio transmitters. This test procedure involves the use of a signal generator and a signal receiver to generate a test signal at a frequency of 1 kHz and 5 kHz, respectively. The generator is connected to a power port, and the receiver is connected to a ground port. The test equipment is designed to measure the immunity of the equipment to EMI from the test signal.

The fourth test procedure is called "IEC 61000-4-13:2019-4," also known as "Class D," which is designed to simulate immunity from EMI caused by both low-frequency and high-frequency sources. This test procedure involves the use of a signal generator and a signal receiver to generate a test signal at a frequency of 1 kHz and 5 kHz, respectively. The generator is connected to a power port, and the receiver is connected to a ground port. The test equipment is designed to measure the immunity of the equipment to EMI from the test signal.

Conclusion:

IEC 61000-4-13:2019 is an essential international standard that provides guidelines for conducting electromagnetic compatibility tests.
