Title:
POWER SUPPLY CONTROL CIRCUITRY, ELECTRONIC SPEED REGULATOR, UNMANNED AERIAL VEHICLE, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2017/128113
Kind Code:
A1
Abstract:
Power supply control circuitry comprises: a capacitive load circuit (11), a switch circuit (12), and a time delay control circuit (13). The capacitive load circuit (11) and the time delay control circuit (13) are connected in parallel between a power supply positive electrode (14) and a power supply ground (15), and the switch circuit (12) and capacitive load circuit (11) are connected in series and are electrically connected to a control terminal of the time delay control circuit (13). The time delay control circuit (13) is used to control, after a power-on time between the power supply positive electrode (14) and the power supply ground (15) exceeds a preset duration, the switch circuit (12) to switch from high impedance output to low impedance output. Also provided is a control method for a power supply output circuit, comprising: after the power-on time exceeds a preset duration, controlling a switch circuit (12) to switch from high impedance output to low impedance output. Further provided are an electronic speed regulator and an unmanned aerial vehicle using the power supply control circuitry or control method. The power supply control circuitry, electronic speed regulator, unmanned aerial vehicle, and power supply control method of the present invention can simplify electrical spark prevention operations during hot-plugging of an unmanned aerial vehicle.
