Latest Patents

Zhelev’s patent, “De-exciting system for inductive circuits,” describes a system designed to dissipate energy from an inductive circuit containing at least one coil. The system uses a discharge resistor and a unidirectional discharge switching element connected in series, along with a unidirectional bypass switching element connected in parallel with the resistor.

The control device operates the system in two phases. In the first phase, it switches both switching elements into a conducting state, creating a closed path through the coil and the switching elements. In the second phase, it switches the bypass element off while keeping the discharge element conducting, allowing energy to dissipate through the discharge resistor.

Career Highlights

Zhelev’s listed patent focuses on controlling the discharge of energy stored in inductive circuits. Its two-phase switching arrangement provides a way to establish a conducting path and then direct the discharge through a resistor.
