Abstract

The invention discloses a voltage stabilization method applied to output of a piezoelectric transformer. At least one voltage stabilizing diode which works in a reverse breakdown voltage stabilization area is connected at an output end of the piezoelectric transformer or to a rectification circuit of the output of the piezoelectric transformer, so that a voltage stabilization loop connected in parallel with an output load is formed to realize voltage stabilization output. The circuit structure is simple, and the output load regulating capacity of the piezoelectric transformer can be improved; therefore, the requirement on product miniaturization can be met.

Description

technical field [0001] The invention relates to a method for stabilizing voltage at an output terminal; in particular, it relates to a method for stabilizing voltage suitable for the output of a piezoelectric transformer. Background technique [0002] Piezoelectric ceramic transformer is a new type of piezoelectric transducer, which has the advantages of small size, simple structure, non-combustibility, radiation resistance, no electromagnetic interference, built-in short-circuit protection, and high reliability. It is currently an ideal device that can replace electromagnetic transformers. However, when the piezoelectric transformer is open-loop, the output load regulation ability is poor, and the output voltage has a poor output load regulation rate, which cannot be used in occasions with large load changes. [0003] The block diagram of the working principle of the existing common piezoelectric transformer output voltage stabilization method is as follows: figure 1 As s...
