Closed‐Form Solution for Zero‐Volt Loop Electromagnetic Energy Conversion in Non‐Linear Switched Reluctance Machines

ABSTRACT

The magnetically non‐linear switched reluctance (SR) machine energy conversion optimisation is a challenging computational task due to the non‐linearly varying current and torque and the presence of numerous design and operating parameters. Zero‐volt loop (ZVL) control of the SR machine is an effective mode of operation that optimises torque production and minimises the magnetic and the switching losses. This paper presents a mathematically simple and computationally rapid optimisation method that enables accurate search of energy conversion for the ZVL control mode of a given SR machine design.
