The role of the current loop of the Tricycle With Cabin controller

Due to the cooperation of the double closed loop, the motor can achieve the most ideal starting process and acceleration process, so that the battery current can be effectively utilized, thereby increasing the driving mileage of the Tricycle With Cabin. Due to the effect of the current loop, the driving distance can be extended by nearly 10% compared to the controllers commonly used on the market. The effect of the current loop is more obvious when there are frequent accelerations and decelerations, and repeated ups and downs during driving.

The controller adopts a double closed-loop control system. Due to the existence of the current loop, the current limit can be realized, that is, the maximum current output value of the Tricycle With Cabin can be protected from exceeding the set current limit value under various normal operating conditions. Automatic current limiting, so that under any operating conditions, the battery will not discharge beyond the set value current, ensuring the safety of the battery.
Since the controller is a single closed-loop control system and relies on the current limiting function of the MC33035 chip, the controller often outputs large current to the operating state of current limiting protection during startup and acceleration. Some controllers on the market only have an under-voltage protection function, which means that when the battery voltage is lower than a certain voltage value, the controller is blocked and does not work. This easily allows users to use the rising voltage of the battery to work, causing the battery to over-discharge.
Reliable protection can be achieved in both locked-rotor operation and direct short-circuit at the output end, which improves the reliability of the brushless Tricycle With Cabin controller during actual operation. The improved controller can completely reduce the failure rate of the controller and reduce the The purpose of vehicle repair rate.
The under-voltage comparison of this controller is designed as a voltage hysteresis self-locking comparison, which can effectively avoid the use of battery voltage recovery. It has been proven to have high reliability through actual driving tests under various load conditions and various road conditions.
