摘要

由于结构简单，维护成本较低，电动汽车在这个次大陆很受欢迎。作为乘用车，轻便自行车在孟加拉国被广泛使用。主要是使用效率低于80%的铁芯变压器为1000多万辆简易自行车充电。这些低效的充电器给国家电网造成了巨大的电力损失。此外，这种传统充电器的手动控制对用户来说很麻烦。基于电力电子的充电器的实现能够以90%以上的效率运行，这可以减少公用事业电网的功率损失。提出了一种内置智能系统的高容量同步降压变换器充电器。自动充电电流控制系统启动。利用PSIM软件进行仿真，搭建了轻便型简易自行车充电器样机，并对其输出电流大的性能进行了评价。对其效率和最大额定功率进行了观察，并与传统充电器进行了比较。

A high capacity synchronous buck converter for highly efficient and lightweight charger of electric easy bikes

For simple structure and lower maintenance cost, electric vehicles are popular in this sub-continent. As passenger vehicles, easy bikes are being widely used in Bangladesh. Mainly, iron core transformer based bulky chargers with efficiency lower than 80% are used to charge more than 10 million easy bikes. These inefficient chargers cause huge power losses to national utility grid. Moreover, manual controls of such conventional charger are bothersome to its user. Implementations of power electronics based chargers are able to operate in more than 90% efficiency which can reduce the power losses from utility grid. A high capacity synchronous buck converter based charger with built in intelligent system is proposed in this paper. An automated charging current control system is initiated. After the simulation by using PSIM software, a lightweight prototype of easy bike charger is built and its performance is evaluated for high output current. The efficiency and its maximum rated power is observed and compared with the conventional charger.
