Electronic battery switch for UAV BLDC motor

Popis výsledku v původním jazyce

The development of unmanned aerial vehicles (UAV) is impossible without optimizing brushless direct current (BLDC) systems and increasing their specific power. To increase power, it is rational to boost the operating voltage while reducing the current and heat dissipation of the stator. However, the impedance of the stator windings and their inductance limit the use of higher operating voltage. High-voltage BLDC motors at low speeds operate inefficiently due to too short pulse-width modulation (PWM) pulses leading to large thermal losses on the output FET transistors. Solutions used in practice in the form of electromechanical switches designed for low operating current or built on a single cascade have low efficiency. This article describes the design of a new high power electronic battery switch that allows efficient use of high voltage BLDC motors at any speed in dynamic mode. This allows for a significant increase in the operating time of the BLDC motor from a single battery charge without the need for additional batteries or recharging of existing ones. Since modern LI-Pol batteries are very expensive and have a limited charge-discharge cycle lifespan, electronic battery switches allow for embedding them into finished products to increase battery life and reduce the final cost of BLDC systems. In particular, it allows the UAV to stay airborne for much longer or use batteries with lower capacity and weight.
