    A DC voltage divider is a power converter composed of capacitors, diodes and switches. It is a one-way transmission device. It can divide the input high voltage under the working conditions of alternating input and output. , DC low voltage output, its input and output impedance transmission ratio is N², "N" indicates the number of capacitors it contains. Compared with the traditional AC transformer, the present invention has a complementary relationship in characteristics and can replace the voltage-reducing function of the transformer in power equipment.
