Modularized rod-controlled power supply of nuclear reactor

The invention discloses a modular rod control power supply of a nuclear reactor, and relates to the field of reactor fuel control, a main power phase dislocation parallel circuit is designed to output sequential control current to a driving coil to act on the driving coil, the main power phase dislocation parallel circuit is a four-phase circuit, the first phase is a host, the remaining three phases are slaves, and the host is connected with the slaves in parallel; the four-phase staggered-phase parallel circuit is adopted, the control mode of each phase circuit is master-slave current sharing, and compared with the prior art that one path of IGBT chopping output is used, the four-phase circuit equally divides current stress and voltage, all power losses are evenly distributed on all phase circuits, the losses on each phase element are smaller, and the power efficiency is improved. The voltage applied to the switching tube by the circuit is relieved, so that the loss of the switching tube is reduced, and the
