Title:
スナバ回路及びそれを用いた電力変換システム
Document Type and Number:
Japanese Patent JP6706811
Kind Code:
B2
Abstract:
A snubber circuit configured to suppress loss to a low level and a power conversion system including the snubber circuit are provided. When a magnitude of a voltage between a pair of first voltage points (P11, P12) in a main circuit exceeds a first clamp value, a first clamp circuit (31) absorbs electrical energy of the main circuit from the pair of first voltage points (P11, P12) to clamp the voltage to the first clamp value. When a magnitude of a voltage between a pair of second voltage points (P21, P22) in the main circuit falls below a second clamp value, a second clamp circuit (32) injects electrical energy to the main circuit (2) from the pair of second voltage points (P21, P22) to clamp the voltage to the second clamp value. A voltage conversion circuit (33) performs voltage conversion between a first clamp voltage (Vc1) defining a first clamp value and a second clamp voltage (Vc2) defining a second clamp value.
