Abstract

The invention discloses a magnetically integrated hybrid distribution transformer using a current source type converter, comprising a current source type converter unit, a main transformer and an isolation transformer. The current source converter unit is composed of the control bridge arm and the DC bus inductance; the iron core is composed of an iron yoke, a leakage magnet core and an iron core column wound with windings; Divided, reversely wound inductive sub-windings. Each iron core column has two sections of sub-windings connected in reverse series to form a group of inductances, and then each group of inductances are connected in reverse series to form a complete converter bus inductance. The magnetic decoupling between the converter bus inductance and the transformer winding is realized.

Description

【Technical field】 [0001] The invention belongs to the technical field of transformers, and in particular relates to a magnetically integrated hybrid distribution transformer using a current source converter. 【Background technique】 [0002] Hybrid distribution transformer is a new type of distribution transformer. It improves the design of traditional distribution transformers by combining power electronic devices, so that it not only has the advantages of high efficiency and reliability of traditional distribution transformers, but also greatly improves the controllability of distribution transformers, so it is very suitable for future distribution networks. intelligent development needs. [0003] The converters of the current hybrid distribution transformers mostly use voltage source converters. However, the voltage-type converter contains a large DC bus capacitor, which has low reliability, low energy density, short life and easy damage; in addition, the capacitor is lar...
