4 FAQs about Inverter intermediate DC link

What is a DC link in a traction motor inverter?

The DC link buffers this power, providing a smooth intermediate DC voltage so the inverter can convert it into grid-compliant, stable AC electricity. The technology is also used in Electric Vehicles (EVs), where the DC link manages the power flow between the high-voltage battery and the traction motor inverter.

What is a DC link in a power converter?

The core function of this link is to establish a stable, regulated DC voltage bus, ensuring the smooth operation of the downstream electronics. The DC link effectively decouples the input power source from the output load, allowing each stage of the power converter to operate independently.

Which EV subsystems have DC link capacitors?

Another EV subsystem where DC link capacitors are found is the inverter in motor drive circuits (shown in Figure 3). The inverter converts DC power from the battery to three-phase AC power to drive the traction motors during acceleration, and then converts AC power back to DC during braking.

What is DC link voltage?

DC link voltage: This is the voltage that prevails in DC links. This voltage fluctuates due to the continuous input and output of energy and is adjusted in each case by means of the adjacent converters. DC link capacitor: This is the actual energy storage device. Pre-charging circuit: In a DC link, this circuit consists of electrical resistors.
