Selection of parameters of the circuit shuntable switch of DC inductive current
The analysis of the parameters of the shunt disconnecting inductive load of direct current, the dependence of the switching voltage on the structure and parameters of the shunt, the characteristics of the process of disconnecting the inductive load by shunting. It is established that in the process of shutdown, close to optimal, the switch should behave like a sequential rC-circuit. The parameters of the shunt circuit depend both on the parameters of the load r and L, and on the capacitance of the capacitor installed in the shunt circuit. Current suppression before switching voltage minimization is realized due to the priority of minimizing leaked charge. Offered instead of rigid restrictions on the characteristics of the process of switching off, softer, integral constraints. The type of voltage found under these conditions allows us to determine the structure of the shunta and the parameters of its elements.
