Power high frequency driver of ESC controller UAV
Original language description
One way to increase the power of Brushless Direct Current (BLDC) motors is to switch to ferrite stator cores and increase the Pulse Width Modulation (PWM) frequency of Electronic Speed Controllers (ESC). This is particularly important in UAVs, where the weight of BLDC motors and their specific power are critical. The main problem when operating at high PWM frequency is that all parallel-connected MOSFETs should turn on quickly and in perfect synchronism. Non-synchronization of transistors leads to thermal or electrical breakdown. The paper proposes new circuit solutions that ensure synchronous operation of high-power MOSFET transistors in the output stages and allow increasing the PWM frequency of electronic speed control controllers (ESC) to 150-200 kHz. The use of ferrite cores in stators will significantly increase the power of BLDC motors while maintaining the same dimensions. Increasing the PWM operating frequency also allows multi-pole BLDC and PMSM motors to operate at higher speeds. The paper reveals a comprehensive methodology for constructing high-frequency ESC controllers for UAVs when switching to ferrite stator cores of BLDC motors. A special contribution is the description of the protective cascade circuits and the Battery Elimination Circuit (BEC) for powering the microprocessor part from a high-voltage current source.
