Abstract
The present invention is directed to a RF transmit system () for a magnetic resonance examination system where it is intended to provide a solution for the problem of rapidly switching between operation modes of different peak power requirements at good power efficiencies. For this purpose the RF transmit system () comprises at least one RF channel () wherein the RF channel () has an RF amplifier (), at least two power supply devices () wherein each of the power supply devices () is configured to supply a voltage to the amplifier (). The RF transmit system () further comprises a DC switch () configured to switch the voltage supplied to the amplifier () between the power supply devices () and a controller () configured to switch the voltage based on sensor data.
