ABSTRACT:
The provided current source inverter includes a buck converter having an input capacitor and an output inductor, receiving a DC input voltage, and generating an output inductor current, a DC/AC converter having an output capacitor, receiving the output inductor current and generating an AC output voltage, a load coupled to the DC/AC converter, and an energy clamp circuit coupled to the buck and the DC/AC converters. The energy clamp circuit includes a first diode and a second diode, provides a discharging route while the load is disconnected with the output capacitor such that the electrical power stored at the output inductor could be discharged to the output capacitor and the input capacitor and avoids an inrush current.
