Abstract (en)
[origin: WO2007053569A1] A system (200) and method are provided for delivering power to a dynamic load (260). The system includes a power supply (210) providing DC power having a substantially constant power open loop response, a power amplifier (220) for converting the DC power to RF power, a sensor (240) for measuring voltage, current and phase angle between voltage and current vectors associated with the RF power, an electrically controllable impedance matching system (250, 252) to modify the impedance of the power amplifier to at least a substantially matched impedance of the dynamic load (260), and a controller (230) for controlling the electrically controllable impedance matching system (200). The system (200) further includes a sensor calibration measuring module for determining power delivered by the power amplifier, an electronic matching system calibration module (252) for determining power delivered to the dynamic load, (260) and a power dissipation module for calculating power dissipated in the electrically controllable impedance matching system.
