摘要
微功耗电动汽车动力系统最大优点是,只要把输入功率中极小部份进行传统功率变换,就可以得到全部输出功率,即输入功率中绝大部份既不必进行实际的功率变换,也不必通过磁芯变压器或电感传递,直接到达输出端,成为输出功率,这部份输入功率的变换效率可视为100%;同时主功率器件不采用PWM脉宽调制技术,不产生EMI干扰,电路简单,因此功耗极小而寿命极长,安全可靠,节能环保,成本、体积、重量、功耗都是传统电动汽车动力系统的十分之一。
The best merit of the microloss electric vehicle power system is that it takes a small portion of input power through traditional power conversion process and obtains total output power, i.e. most portion of input power could connect to output terminal and become output power, neither through power conversion process, nor through linear transformer or inductor transmission process. This part of the input power conversion efficiency can be regarded as 100%; while the main power devices do not use PWM pulse width modulation technology, it does not produce EMI interference, and uses simple circuit, so the power consumption is very small while the lifetime can be extremely long. It is safe, reliable, energy saving and environmentally friendly with one-tenth of the traditional system＇s cost, size, weight and power consumption.
