Controller by a peripheral device and the main chip (Or single chip microcomputer)Composition. Peripheral devices are some functional components, plant protection unmanned aerial vehicle (uav) power system, such as execution, such as sampling, model aircraft, motor resistance, sensor, a bridge type switch circuit, and auxiliary microcontroller or application-specific integrated circuit to complete process control device; Microcontroller is also called the micro controller, is a integrated on a chip in the storage, transformation decoder, sawtooth wave signal generator and function of pulse width modulation circuit and can make the switch circuit power tube conduction or cut-off, by square wave control conduction time of power tube to control the drive circuit of the motor speed, input and output ports, such as integrated together, and a computer chip. This is the smart electric bicycle controller.
controller design quality, features, the functions of the microprocessor, adopted by the power switch device circuit and peripheral devices such as layout, is directly related to the vehicle's performance and running state, also affect the controller itself performance and efficiency. Different quality controller, used in the same car, with the same set of battery state of charge and discharge, sometimes shows a big difference on the limited driving ability. at present, the electric bicycle controller circuit principle adopted by the same or close to. With brush and brushless dc motor are mostly using pulse width modulation PWM control method for speed control, just choose driver circuit, integrated circuit, power transistor switch circuit, and some differences in related functions. Components and circuit, the controller performance.
