| description | Unique systems, methods, techniques and apparatuses of power amplifiers are disclosed. One exemplary embodiment is a power system for an active magnetic bearing including at least one power amplifier. Each power amplifier includes a first semiconductor device including a first node coupled to a neutral point node and a second node, a second output node coupled to the neutral point node, a second semiconductor device including a first node coupled to the second node of the first semiconductor device and a second node coupled to a first output node, a third semiconductor device including a first node coupled to a first DC bus node and a second node coupled to the first output node, and a fourth semiconductor device including a first node coupled to a second DC bus node and a second node coupled to the second node of the first semiconductor device. |
