摘要： A single-phase voltage source AC/DC converter according to the present invention generates a second axis voltage command from difference between a DC voltage detection value at a DC terminal and a DC voltage command value and controls a DC voltage by increasing and decreasing active power with the second axis voltage command. For example, the voltage at the DC terminal is increased by decreasing active power when the DC voltage detection value at the DC terminal is lower than the DC voltage command, while the DC voltage detection value at the DC terminal is decreased by increasing the active power when the DC voltage detection value at the DC terminal is higher than the DC voltage command.

摘要： An instrument power controller (120) for adaptively providing an output voltage VO and an output current IO that together maintain a substantially constant electrical output power PO is provided. The controller (120) includes inputs (121) for receiving an input power PI, outputs (122) for providing the substantially constant output power PO to a variable impedance load L, and a communication path (126) for receiving a load voltage VL. The instrument power controller (120) is configured to determine an input voltage VI and an input current II, determine an effective resistance RL of the load L and set the output voltage VO and the output current IO based on the input voltage VI, the input current II, and the effective resistance RL. The output voltage VO is substantially independent from the input voltage VI. The output voltage VO and the output current IO are varied to maximize a load power PL while maintaining the substantially constant electrical output power PO.
