What is the difference between dual motors and single motors of pure electric vehicles

For electric vehicles, one of the core components is the motor. The power supply provides electrical energy for the motor, and the function of the motor is to convert the electrical energy into mechanical energy, and then drive the wheels forward through the transmission device. Therefore, the energy conversion efficiency of the car is inseparable from the performance of the […]

170W Voltage Doubler in 23mm x 16.5mm Package

Design Essentials DN571 – Introduction For high voltage input/output applications, inductorless switched capacitor converters (charge pumps) can significantly improve efficiency and reduce solution size compared to traditional Inductor-based buck or boost topologies. By replacing the inductor with a charge pump, a “crossover capacitor” can be used to store and transfer energy from the input to the output. The energy density […]
