Abstract

The device and principle of operation of the pulse modulator, which is the power-supply system for the ILU series accelerators, as well as some features that arise during its operation, are described. The modulator is a device that is a nonlinear load for the supply network, as a result of which, in all phases of the supply network, an asymmetry of the current form occurs over the period of the network. This leads to the appearance of a constant current component in the phases of the supply transformer. To solve this problem, current balancing of the start time of modulators was proposed. Using this method, it is also possible to equalize the values of effective currents in phases. Another problem is the possibility of the appearance of higher harmonics in relation to the supply frequency in the phases of the power-supply network. To reduce the values of higher harmonics, it is proposed to install additional inductances in each phase of the power-supply network up to the modulator, which makes it possible to reduce the harmonic coefficient by half.
