An electrical amplifier comprising several partial amplifiers, which are so connected and voltage fed that each of them amplifies a voltage interval of an input voltage, wherein every partial amplifier is power fed by two supply voltage equipments, which may have the same polarity and are connected to different active components in the amplification unit of each partial amplifier. This gives great flexibility, considerable simplification in mode of operation and possibility to improve the degree of efficiency and reduces the distortion through simple means, especially at the occurence of reactive loads. |
