Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a UAV electronic controller using a silicon carbide transistor. Background Art

[0002] Semiconductor technology has been a decisive force driving the development of the power electronics industry. While the application of power silicon devices is already quite mature, with growing industry demand, silicon devices, due to limitations in their physical properties, have become unsuitable for some high-voltage, high-temperature, high-efficiency, and high-power density applications. Silicon carbide (SiC) has begun to attract attention and research due to its superior physical properties. Since its discovery by Swedish scientists in 1824, SiC was not truly incorporated into solid-state device research until the latter half of the 1950s. Since the 1990s, SiC technology has developed rapidly. The rapid development of SiC field-effect transistor (FET) technology since the 1990s has attracted widespread attention to this new generation of power devices. Compared to silicon, SiC's higher thermal conductivity determines its high current density characteristics, while its wider bandgap contributes to the high breakdown field strength and high operating temperature of SiC devices. Especially in the development and application of silicon carbide field-effect transistors, compared with silicon field-effect transistors of the same power level, silicon carbide field-effect transistors have greatly reduced on-resistance and switching losses, making them suitable for higher operating frequencies. In addition, due to their high-temperature operating characteristics, their high-temperature stability is greatly improved.

[0003] In this regard, China has applied for patent number CN113253790B, which discloses a silicon carbide transistor UAV electronic speed controller. The SBUS bus input module, MCU main control circuit module, three-phase gate driver module and silicon carbide power circuit module of the silicon carbide transistor UAV electronic speed controller are connected in sequence, and its input end is also connected to the power circuit module. The output end of the bus voltage measurement circuit module, the output end of the temperature measurement circuit module and the output end of the phase voltage acquisition circuit module are respectively connected to the MCU main control circuit module. The brushless motor is connected to the input end of the phase voltage acquisition circuit module and the output end of the silicon carbide power circuit module. The input end of the bus voltage measurement circuit module is connected to the battery module. The silicon carbide transistor UAV electronic speed controller provided by the present invention can make the UAV flight operation stable and reliable for a long time, reducing the risk of damage to the electronic speed controller due to overheating.
