1、DC-Link简介 DC-Link,全称直流母线(Direct Current Link),是连接整流器与逆变器的关键环节,承担着能量缓冲、电压稳定和滤波的重要职责。尤其是在变频器、逆变器、马达控制器、不间断电源(UPS)和可再生能源系统(如太阳能和风能发电系统)中,起到至关重要的作用。 近年来,随着超级电容器技术的快速发展,将其应用...
1 0 x 2ir Derivation of DC link current in a 3-phase PWM inverter HVIIMIJlfflriJl It is of interest to know the current waveform drawn from the DC line of a pulse-width modulated (PWM) inverter. This is partly because it improves the general understanding of inverter operation, but ...
DC-Link Current Measurements VinGan Level 2 27 Feb 2025 Hi, We are running a custom board and we are able to run the motor using the Keil TLE9879 FOC example.Can anyone help us to find which are the variables that points to DC-Link current and voltages?Kind regards VG Solved!
The dc-link current in pulsed power inverters for all modulation procedures has a substantially ac-portion. This current heads up the dc-link capacitors and must be considered for the inverter dimensioning. As these capacitors have a major impact on the volume, weight and costs of the inverters...

A general method is described for calculating the current drawn by an inverter from its DC source. It has special relevance to pulse-width modulated inverters and allows the ripple current rating of the filter capacitor to be specified with some precision. The method is for an inverter of any...
摘要: Both the spectral analysis and the closed-form root-mean-square (RMS) equations are widely used to determine the three-phase inverter dc-link current for capacitor rating proposed. However, the analytical models of the dc-link currents have rarely been r...
