保持颜色效果需要稳定的电流；因此，当车辆关掉时，顺磁漆不工作，车辆切换回默认的白色。

A steady current is needed to maintain the color effect, thus the paramagnetic paint doesn't work when the vehicle is turned off and hence the vehicle switches back to a default white color.

当输出滤波电感的电流在一个周期内不连续时，移相全桥PWM变换器就工作在电流断续模式（DCM）。

Phase-shifted full-bridge PWM converters work in discontinuous current mode (DCM), when the current of out-put filter inductor is discontinuous in one switching period.
