The NTAC-02 speed encoder module DC/DC converter converts a fixed DC voltage into a variable DC voltage. This technology is widely used in the continuously variable transmission and control of trolleybuses, subway trains, and electric vehicles, while achieving stable acceleration and fast response performance, while also achieving the effect of energy conservation. Replacing a rheostat with a DC chopper can save (20-30)% of electrical energy. The DC chopper can not only regulate the voltage of the switching power supply, but also effectively suppress the harmonic current noise on the power grid side. The secondary power supply DC/DC converter for communication power has been commercialized, and the module adopts high-frequency PWM technology. The switching frequency is around 50OkHz, and the power density is 5W~20W/in3. With the development of large-scale integrated circuits, miniaturization of power modules is required. Therefore, it is necessary to continuously increase the switching frequency and adopt new circuit topologies. Currently, some companies have developed and produced secondary power modules that use zero current switching and zero voltage switching technology, with a significant increase in power density
