Low-inductance AC capacitor for high power traction motor drive inverters

Short Description:

This AKMJ-S series capacitor is used to absorb and store energy when the AC power is higher than what is needed by the DC load, and to supply energy to the load when the AC power is lower than what is needed.

Maximum aititude

2000m

When the altitude is above 2000m to below 5000m, it is necessary to consider the use of a reduced amount.

(for each increase of 1000m, the voltage and current will be reduced by 10%)

Life expectancy

100000h(Un; Θhotspot≤55°C)

Reference standard

IEC 61071 ;IEC 60831;

Feature

1. Metal case package, Sealed with resin;
2. High voltage power system application;
3. High power circuit;
4. Resistance to high voltage, with self-healing;
5. High ripple current, high dv / dt withstand capability.

Function

In the output filter of a DC power supply, the job of the capacitor is to maintain a constant DC value by removing as much power ripple as possible.

All AC-DC converters, whether they are linear supplies or have some kind of switching element to them, require a mechanism to take the varying power on the AC side and produce a constant power on the DC side.
