Laminated busbar for power converter and the converter thereof

摘要

The present application discloses a laminated busbar arrangement for use in a three-level power converter and a power converter. The laminated busbar arrangement comprises a first layer of busbar comprising a neutral-point sub busbar congfigured to make electrical connections between respective components in the three-level power converter and a neutral-point potential; a second layer of busbar comprising a plurality of sub busbars congfigured to make electrical connections between the respective components in the three-level power converter and a positive direct current (DC) input, a negative DC input and an alternating current (AC) input/output in the three-level power converter, and between respective semiconductor switching components. The present application may effectively reduce stray inductance. chbm A01 26721758 120390260 P r S11|I FWD,, 0110 __ ___ _ :12K1 C13 13 D12 2 "S131 FWD 13 I(1 : C16 D15 S S161 FWD1 1 5A E1- ------- 16: C2 --------- ------------------ I-I S14-| FWD4 Fig.4A Fig.4B chbm A0126772120-v1 120390260
