| 发明名称 | Drive circuits and systems for motor controller protection | ||
| 摘要 | Protection of a motor controller from a transient voltage and/or an over-voltage condition is described. A drive circuit includes a rectifier portion and at least one inductive device coupled to the rectifier portion. The drive circuit further includes at least one voltage clamping device coupled in parallel with the at least one inductive device, and at least one switching device configured to open as a function of a direct current (DC) link voltage value. | ||
