Abstract

This paper considers the main stages of operation of a three-phase voltage-source inverter and its constituent parts in the soft switching mode. It has been shown that the power transmitted to the load depends not only on the duration of the open state of the main switches of the inverter, but also on the duration of the operation of its auxiliary transistors, as well as on the amount of stored energy in the resonant circuit. The conditions for the fulfillment of the balance between the power consumed from the source and the power transmitted to the load have been determined. The paper shows that, according to the results of calculating the components of the power balance at individual intervals of operation, it is possible to determine the equivalent duty ratio for the power switches of the inverter in analytical form. Taking into account the equivalent duty ratio in the synchronous coordinate system, a continuous mathematical model of a three-phase voltage inverter with soft switching has been constructed and presented in the form of an equivalent electrical circuit. The calculation of the equivalent electrical circuit shows that the balance of power consumed from the power source and the power supplied to the load is true not only for the voltage inverter as a whole, but also for its main nodes. The equations of the mathematical model make it possible to develop inverter control systems with a current control loop, as well as multiloop systems of subordinate control. The solutions of the equations of the mathematical model under direct current and in the frequency range determine the dynamics and stability of the control process.
