Embodiment Construction

[0029] The present invention will be further described below in conjunction with drawings and embodiments.

[0030] 1. Proposed PFM immunity generator calibration method

[0031] The main parameters that characterize the PFM immunity generator are as follows: ① output current value, ② output current total harmonic distortion rate, ③ coil factor, ④ coil test area. For each type of parameter, different calibration circuits and calibration procedures are required due to the different characteristics of the parameters.

[0032] ① Output current value calibration test circuit: such as figure 1 As shown, the PFM immunity generator 1 is connected to the 1-meter standard coil 4 through the twisted pair 3 not exceeding 3 meters, the current probe 2 is clamped at the output end of the PFM generator, and the output signal of the current probe is connected to the oscilloscope 5 . ② Output current total harmonic distortion calibration test circuit: such as figure 2 As shown, the PFM im...

Abstract

The invention provides a calibration system and a calibration method for a power frequency magnetic field noise immunity generator. The calibration system comprises a PFM (power frequency magnetic field) noise immunity generator, a current probe, a square coil, an oscilloscope, a harmonic monitor, a magnetic field probe and a magnetic field receiving device. The calibration method is characterized in that major parameters of the PFM noise immunity generator comprises four types as follows: (1) an output current value, (2) the total harmonic distortion of an output current, (3) a coil factor, and (4) a coil test area, and the four types of parameters are calibrated through different calibration lines and calibration programs. By adopting the calibration system and the calibration method disclosed by the invention, the quality and the efficiency of quantity transmission of the PFM noise immunity generator are improved effectively.

Description

technical field [0001] The invention relates to the technical field of electromagnetic compatibility tests, in particular to an automatic calibration system and a calibration method for a power frequency magnetic field (PFM for short) immunity generator used in electromagnetic immunity tests. Background technique [0002] The PFM immunity test is one of the main contents of the electromagnetic compatibility test project of electrical and electronic equipment, and the electromagnetic compatibility test has been included in the national compulsory certification category. The PFM immunity generator is the main standard device for implementing PFM tests. In order to ensure the quality of the PFM immunity generator and its accuracy and reliability during use, it is very necessary to calibrate it scientifically and effectively. Therefore, it is particularly important to study the calibration method of the PFM immunity generator and design a corresponding automatic calibration syst...
