Active waveform-controllable magnetic source electromagnetic transmitter system and control method

The invention discloses an active waveform-controllable magnetic source electromagnetic transmitter system and a control method. According to the system, a main control circuit (2) generates a switching signal, and a drive circuit (3) performs isolation amplification on the switching signal so as to provide an on-off time sequence; an external direct-current power supply (1) is used for continuously providing direct-current voltage for a boost circuit (4), transmitting current is provided for a transmitting coil (8) during the rising edge period and the plateau period of the transmitting current through a buck circuit (5) and a full-bridge emission circuit (6); a double-diode clamping circuit (7) provides an energy feedback path during the falling edge period of the transmitting current and provides high-voltage clamping for the transmitting coil (8), and energy fed back by the transmitting coil during the falling edge period of the transmitting current is stored in a capacitor of the boost circuit (4); and a
