Abstract
Disclosed is a manual inverse power supply, comprising a transformer, a band switch, a charging switch, a control relay, a high power module, a full-wave rectification bridge, and a pulse width modulation circuit. The transformer is wound with an inverse charging winding and a commercial power winding. The band switch is a three-position switch of the conversion of the commercial power, close down, and inversion. The inverse charging winding can be connected with the commercial power by the band switch and a first control relay, or by the charging switch and a second control relay. Owing to the integration of a plurality of switch combination modes, the utility model has the advantages of safety, convenience and reliability. As an emergency power supply, the utility model is suitable for microcomputer system, communication system, hospital, alarm system, family illumination, television and the other situations which require low power utilization of power.
Description
Affiliated technical field
The utility model relates to a kind of inverter, refers in particular to a kind of inverter that can manual switch.
Background technology
At present, the domestic situation that shortage of electric power occurs, full-automatic inverter has just become the market best-selling product.But because commercially available full-automatic inverter exists such problem when automaticallying switch: in case after having a power failure, automatic inverter just inversion immediately changes into the voltage output of 220V to electric power supply with cell voltage, because efficient and power problem during inversion, the inverter load capacity is limited, so just caused often heavy load electrical equipment being received on the inverter because of the user, and forget and turn off, thereby damaged inverter.
The utility model content
The purpose of this utility model is to overcome the above-mentioned defective of prior art existence, and a kind of manually contrary power supply is provided, and it has safety, convenient, reliable advantage, uses as emergency power supply.
For achieving the above object, the solution that the utility model is taked is: a kind of manually contrary power supply, it comprises transformer, band switch, charge switch, control relay, high power module, full-wave rectification bridge, pulse-width modulation circuit, on transformer, be wound with inversion charging winding and two groups of windings of civil power winding, band switch is civil power, shutdown, inversion conversion three-position switch, inversion charging winding can pass through band switch, first control relay is electrically connected with the city, also can pass through charge switch, second control relay is electrically connected with the city.
Because the utility model has been concentrated a plurality of switch combination modes, have safety, convenient, reliable advantage, as emergency power supply, be applicable to that microsystem, communication system, hospital, warning system, domestic lighting, TV and other need the place of small-power electricity consumption.
Its operation principle is summarized as follows: during use, receive the input of inverter on the commercial power socket or the family expenses kilowatt-hour meter below.When the city, band switch is placed city's electric position, at this moment the first control relay coil gets electric its first contact adhesive, this moment, civil power was directly exported, and second contact communicates with the lead-out wire of Transformer Winding, if when charge switch placed charge position, the second control relay coil gets electric its contact adhesive, civil power one tunnel charging, a road direction electric; At this moment, if having a power failure, owing to not being in inversion dislocation, band switch do not have to connect, so the back pulse-width modulation circuit that has a power failure is inoperative with pulse-width modulation circuit; Have only band switch is manually switched to inversion dislocation, the position that charge switch is placed out simultaneously, the pulse-width modulation circuit starting of oscillation, inverter begins operate as normal; The user can turn off the heavy load power consumption equipment earlier when having a power failure to manual conversion inversion, thereby guarantees inverter not transshipped and damage; When the user did not need not need inversion with civil power yet, as long as band switch is in stop position, complete machine just can not worked.
Description of drawings
Fig. 1 is the electrical schematic diagram of present embodiment.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1, a kind of manually contrary power supply, it comprises transformer B, band switch K1, charge switch K2, control relay JI, J2, high power module, full-wave rectification bridge, pulse-width modulation circuit PWM, on transformer B, be wound with inversion charging winding B1 and two groups of windings of civil power winding B2, band switch K1 is civil power, shutdown, inversion conversion three-position switch, inversion charging winding B2 can pass through band switch K1, the first control relay J1 and be electrically connected with the city, also can pass through charge switch K2, the second control relay J2 and be electrically connected with the city.
