The invention relates to the field of geophysical exploration equipment, and specifically, relates to a short dead zone magnetic resonance emission device and a control method based on wide configuration harmony. A PC upper computer and a master control module are provided, according to a command of the upper computer, a DC-DC converter is controlled to charge an energy-storage capacitor, and thecharging energy comes from a storage battery; by sending a PWM wave, a H bridge emission module and a coil are controlled to perform bipolar pulse emission, and emission energy comes from the energy-storage capacitor; by controlling a first switch driving module, on and off of a first switch are controlled, by controlling a second switch driving module, on and off of a second switch are controlled, and by control a third switch driving module, clamp voltage of a clamping module is controlled; based on a negation circuit used for negation of a switch control signal of a master control module, complementation is executed for first switch and second switch switch-on signals. The device and the method provided by the invention solve a problem that the signal itself has relatively low amplitude, is almost completely submerged in noise after energy release time decay, brings great difficulty in follow-up data processing and inversion and has strong impact on detection effect, can effectivelyreduce turn-off time of an emission system and reduce dead zone time of magnetic resonance detection, and consequently can improve signal amplitude.
