Embodiment
Below preferred embodiment of the present utility model is described in detail.
The TV set device of the utility model automatic power comprises a television set main circuit and a power module, and described power module connects an inverter by a voltage stabilizing circuit and forms, as shown in Figure 1.Described power module is used for being provided with power detector to the power supply of television set main circuit before described power circuit, is used to detect the abnormal conditions of civil power, and turn-offs civil power when detecting the abnormal conditions of civil power; Described voltage stabilizing circuit is used for civil power is converted to direct current, and described inverter connects described voltage stabilizing circuit and television set main circuit, is used for the dc inverter after the voltage stabilizing circuit conversion is converted to the required alternating current of described television set main circuit; One electricity storage module connects described voltage stabilizing circuit and described inverter, is used for powering to the television set main circuit by described inverter circuit from the charging of described voltage stabilizing circuit and when city's electrical anomaly.
For realizing above-mentioned controlling, also be provided with a control chip in the power detector of the present invention, turn-off civil power when being used to be controlled at city's electrical anomaly, and, when being full of electricity, described electricity storage module stops charging.
Power detector one end described in the utility model connects civil power by controllable switch element K1, and whether detect civil power by described control chip simultaneously unusual; Described control chip can disconnect the cut-out civil power by control switch element K1 under the situation that detects city's electrical anomaly; The described power detector other end is connected to the voltage stabilizing circuit in the power module.Described voltage stabilizing circuit is with electric main rectification, the filtering of input, output DC, and described inverter is by the method for inversion, the direct current of input is converted to the voltage of the required frequency of television set main circuit, and the power module that is provided with described voltage stabilizing circuit and inverter realizes the television set main circuit is provided the alternating current of voltage stabilizing, frequency stabilization by this way.
Described electricity storage module connects described voltage stabilizing circuit and inverter circuit by a controllable switch element K2, and described voltage stabilizing circuit can be described electricity storage module charging in described television set main circuit power supply under the normal situation of civil power.Described electricity storage module inside is provided with a battery and an electric weight self-checking unit, described electric weight self-checking unit can be monitored the charge volume of battery automatically, when battery is full of electricity, can be by the control of the control chip in described power detector off switch element K2, stop to battery charge, in case, battery is caused damage, prolong the useful life of battery to the battery charge transition.
The battery of described electricity storage module can be set to storage battery or ultracapacitor, the method that batteries to store energy and ultracapacitor energy storage are taked all is, earlier AC energy being transformed to direct current energy is stored in storage battery or the ultracapacitor, when needs make the electric energy of stand-by storage, control the conducting of described switch element K2 by described control chip, electric current is converted to described television set main circuit needed alternating current through inverter with direct current energy from energy-storage module.
