Semi-directional regulating circuit

Abstract

The invention provides a semi-directional adjusting circuit, which is used for adjusting output signals of at least an auxiliary circuit of a signal source. The semi-directional adjusting circuit includes a transformer having at least two windings. An output main circuit of the signal source is in series with a first winding of the transformer; the auxiliary circuit requiring signal adjustment is in series with at least the other winding of the transformer. By adopting the technique of the semi-directional adjusting circuit provided by the invention, the voltage adjusting amplitude can be large without loss increase, and thus the invention is beneficial for increasing power efficiency and also the reliability. The semi-directional energy consumption can be controlled through the duty cycle of main circuit adjustment, which is free from the limit by a relatively high quantity or a relatively low quantity of specific output of the auxiliary circuit. The invention can realize complete compensation under the condition that the output of all the auxiliary circuits is relatively low. The voltage adjusting amplitude can be directly used for quantum calculation, without effect from the duty cycle. Besides, the voltage adjusting cost is low, the performance cost ratio is high, and the electromagnetic characteristics of relevant output circuits can be improved as well.

Description

technical field [0001] The invention relates to the technical field of basic electronic circuits, in particular to a semi-directional regulating circuit. Background technique [0002] At present, in the multi-output power supplies used in the industry, due to the existence of transformer turns that can only be integer turns and other factors, especially the number of transformer turns is rounded (for a few special-application transformers, it may be possible to take half turns, but the number of half turns The transformer has special requirements for the air gap mode of the magnetic core, the distribution of the winding, or the way of the winding lead-out wire, which will increase the winding cost of the transformer), and the specific turns of each output winding of the transformer are generally rounded up, and The rounding and rounding of each winding may be inconsistent, and the rounded voltage turns ratio of each auxiliary winding may also be inconsistent with the rounded...

Problems solved by technology

[0005] 1. When a certain output adopts this inductive voltage regulation technology, the reduced energy is compensated to other outputs, including other output channels that have high output but voltage regulation accuracy does not exceed the standard, which may cause these output The output voltage regulation accuracy of the circuit thus exceeds the standard;

[0006] 2. When a certain output adopts this inductive voltage regulation technology, the reduced energy is compensated to other outputs, including the main output with feedback. When the main output voltage is affected to a certain extent, it will inevitably cause duty Therefore, this voltage regulation technology has limited compensation for the output circuit with low output;

[0007] 3. When a certain output channel adopts this inductive voltage regulation technology, the compensation obtained by other output channels is related to the transformer, which is basically fixed and cannot be compensated on demand.
