Abstract
Provided in the present invention are a power control apparatus for a radio-frequency power amplifier and a radio-frequency transmission system for a magnetic resonance imaging system. The power control apparatus comprises: a power control module used to receive a control voltage so as to control an output power of the radio-frequency power amplifier; a voltage detection module used to detect an operating voltage provided to the radio-frequency power amplifier and to output a detected voltage; and a voltage adjustment module used to adjust, on the basis of the detected voltage, the control voltage received by the power control module so as to adjust the output power of the radio-frequency power amplifier.
