Abstract
A kind of quick tolerance purifies highly reliable alternating current steady voltage plug, by input filter, main loop circuit, bidirectional triode thyristor, controller constitutes, it is combined the series compensation voltage stabilizing with adjusting principle of stabilized voltage in parallel, can in 140 volts of-300 volts of scopes of line voltage, be fully loaded with 200 volts of outputs, and when source step or load current step disturbance, have little overshoot voltage and Fast Dynamic transit time, by the redundancy backup of electron device, realized alternating current steady voltage plug fast, functions such as tolerance, purification.
Description
The present invention relates to a kind of Voltage of Regulated industrial Frequency AC Power,, be applicable to that line voltage can export 220 volts of stable voltages in 300 volts when changing for 140 volts particularly to the dynamic response characteristic and the pressure-stabilizing property of wide range of alternating current steady voltage plug.
At present, two kinds of principle of stabilized voltage are arranged in the known voltage stabilizing technique, series compensation principle and Principles of Regulation in parallel.Power conditioner is to adopt sinusoidal energy dispenser to realize voltage stabilizing, and it belongs to the voltage stabilizing of series compensation principle.The tolerance power conditioner adopts input resonant transformation shunting in parallel Principles of Regulation to realize voltage stabilizing.Because their voltage stabilizing mechanism difference respectively has relative merits, power conditioner voltage stabilizing in 185 volts to 242 volts, voltage stabilized range is narrower, and reducing when upper voltage limit along with thyristor operating angle, its dynamic perfromance variation, particularly during the load current step disturbance, output voltage shows damped oscillation, has extended the strain time.The tolerance power conditioner is owing to adopt input resonant transformation shunting in parallel to regulate voltage stabilizing, voltage stabilizing in accomplishing 100 volts to 330 volts easily, but wide more its dynamic response characteristic of voltage stabilized range is also poor more, particularly the excision load disturbance when lower voltage limit will produce big overshoot voltage, transit time is very long, the incompatible electronic equipment that dynamic characteristic is had relatively high expectations.

The purpose of this invention is to provide a kind of can be in wide region voltage stabilizing and alternating current steady voltage plug with Fast Dynamic response characteristic.
The object of the present invention is achieved like this: series compensation voltage stabilizing and the principle of stabilized voltage of regulating in parallel are combined into the compound voltage stabilizing of connection in series-parallel.
Owing to adopted such scheme, the compound voltage stabilizing of connection in series-parallel promptly preserved the series compensation voltage stabilizing good at the lower limit dynamic response characteristic, preserved adjusting voltage stabilizing in parallel in the good advantage of upper limit dynamic response characteristic again, overcome the series compensation voltage stabilizing in upper limit dynamic response characteristic difference and shortcoming of regulating voltage stabilizing lower limit dynamic response characteristic difference in parallel, voltage stabilized range is the characteristics of broad also.
The invention will be further described below in conjunction with drawings and Examples.
