Embodiment
Relevant detailed content of the present invention and technical descriptioon, existing conjunction with figs. is described as follows:
Seeing also shown in Figure 2ly, is integrated information household appliances electric supply installation circuit box schematic diagram of the present invention.As shown in the figure: integrated information household appliances electric supply installation of the present invention, include: a power input unit 1, a rectification unit 2, a boosting unit 3, a converting unit 4, an and load 5, the middle voltage source of being exported by rectification unit 2 is directly inputted in the boosting unit 3, therefore power dissipation is only on boosting unit 3, so can reach the purpose of saving consume, improving usefulness.
The above-mentioned power input unit of mentioning 1 is in order to provide the alternating voltage of 110V to 220V.
This rectification unit 2, input 21 with the above-mentioned AC power of an input, press the direct voltage output about 150DCV to 300DCV during this rectification unit 2 is rectified into AC power, the direct voltage after this rectification is exported by first and second output 22,23 of rectification unit 2 respectively.
This boosting unit 3 is the powerful and inverters of whole effect about 80%, with after first output 22 of above-mentioned rectification unit 2 is connected, the direct voltage that rectification unit is exported can be converted to the alternating voltage output of a high pressure form at the input of boosting unit 3.
This converting unit 4 is connected with second output 23 of above-mentioned rectification unit 2, press the direct voltage that converts a low pressure to (as ± 5V in order to medium voltage DC that rectification unit 2 is exported, ± 12V, ± 24V etc.) 41 outputs, provide required low-voltage dc power supply with other circuit that installs for this reason.
This load 5 can be but be not limited in cold cathode fluorescent lamp (CCFL), ozone generation device, the anion generator any, and load 5 is connected with the output of above-mentioned boosting unit 3, and the high pressure that boosted unit 3 is exported drives.
When above-mentioned power input unit 1 provides an AC power to input to rectification unit 2, this rectification unit 2 can be rectified into this AC power the output of one medium voltage DC source (150DCV to 300DCV), this medium voltage DC source outputs to respectively in boosting unit 3 and the converting unit 4, yet the medium voltage DC pressure that aforesaid boosting unit 3 is exported rectification unit 2 converts a high pressure to about 500V
ACTo 1000V
ACAlternating voltage output, this voltage can drive the load 5 that boosting unit 3 is connected.
Because above-mentioned boosting unit (inverter) 3 with original low pressure commentaries on classics high pressure is designed to press the form that changes into high pressure through boosting unit 3 by the medium voltage DC after rectification unit 2 rectifications, therefore lacked the consume of low-voltage power supply module, usefulness is directly promoted to having only the consume (about more than 80%) of boosting unit 3 itself by 64%, and it is original because unnecessary electric energy will be provided, and the low-voltage power supply module of increasing wattage, also therefore dwindled scale, its usefulness is generally higher because of the efficient of little power supply module again, thereby has obtained tangible improvement.
