Abstract: In view of problems of no storage of electric energy and big volume existed in current transmitter of time-domain induced polarization, a transmitter of time-domain induced polarization based on super capacitor storage was designed. The transmitter uses new circuit topology, which makes the super capacitor store energy output by generator when the transmitter is in idle state, and the super capacitor release the stored energy when the transmitter is in working state. The released energy and the generator provide power for load so as to reduce volume of the generator. Meanwhile the super capacitor connects in series with power supply of the generator when the super capacitor releases the energy, which not only do not need boost inductor but also can realize boost function, so as to optimize volume of the transmitter. The simulation and experiment results show that the transmitter has stable and reliable performance.
