Direct current auxiliary power supply for current expansion type constant current diode voltage dividing

Abstract

The invention discloses a direct current auxiliary power supply for current expansion type constant current diode voltage dividing, comprising M constant current modules and N voltage stabilization modules which are successively in series connection, wherein the head end and the tail end are respectively in connection with a DC power supply input positive terminal HV+ and a DC power supply input negative terminal HV-; M={1,2,...,i...,m}, n={1,2,...,j...,n}, and m>=n>=1; the numbers of M and N are determined based on the principle that any constant current module operates in a constant current work voltage scope, and any voltage stabilization module operates in a voltage stabilization work voltage scope. The direct current auxiliary power supply has the characteristics of simple design, reasonable structure, convenient construction and sound versatility, and can overcome the problem of poor adaptability of a present direct current auxiliary power supply, and effectively realize direct conversion between high and low DC power supplies.

Description

technical field [0001] The invention relates to a DC auxiliary power supply, more specifically, a DC auxiliary power supply involving a current-expanding constant current diode for voltage division. Background technique [0002] At present, the DC auxiliary power supply is mostly used in the low-voltage field, and the technology is relatively mature. However, due to the characteristics of the device and the insufficient withstand voltage performance of the circuit structure, if it is directly applied to a high-voltage circuit, there will inevitably be defects such as complex structure, high manufacturing cost, and poor versatility. Contents of the invention [0003] In view of this, the present invention aims to provide a DC auxiliary power supply with a current-expanding constant current diode voltage divider, which can not only overcome the lack of high voltage adaptability of the existing DC auxiliary power supply, but also effectively realize the direct conversion of h...
