Problems solved by technology

Therefore, although the method of disconnecting the low-frequency transformer can completely remove the excitation loss of the low-frequency transformer, since the battery self-discharge and the control circuit still need to obtain energy from the mains to maintain it, it is necessary to add an additional separate power supply to provide this part of energy, and increase A separate power supply requires higher cost to implement

Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] This embodiment provides a kind of UPS circuit, its structure is as follows figure 2 shown, including the input terminal T that receives AC power from the mains in And the output terminal T that provides AC power to the load out . input terminal T in with output T out There are electromagnetic interference filter EMI, switches SW1, SW2, SW3 and SW4 and low frequency transformer TX between them. Among them, the switch SW3 is used when the UPS uses its battery B to output T out When supplying power, disconnect the low-frequency transformer TX from the mains. The switches SW1 and SW2 are used together to...

Abstract

A UPS circuit, comprising a low frequency transformer (TX) and a battery (B), the low frequency transformer (TX) comprising a primary side winding, and a secondary side winding connected to the battery (B); the primary side winding is connected to a municipal power loop via a switching device (SW), and the switching device (SW) can operate in a chopping mode.

Description

technical field [0001] The invention relates to a UPS circuit, in particular to a UPS circuit with a low-frequency transformer. Background technique [0002] UPS (Uninterruptible Power System, uninterruptible power supply) is an AC power supply that contains energy storage devices. It mainly uses energy storage devices such as batteries to provide uninterrupted power supply to loads during power outages. When the mains input is normal, the UPS will stabilize the mains and supply it to the load. When the mains is interrupted (accident blackout), the UPS will immediately use the energy storage device to continue to supply AC power to the load, so that the load can maintain normal operation and protect the load. Load software and hardware are not damaged. [0003] The basic circuit structure of UPS is as follows: figure 1 As shown, it has an input terminal T that receives AC power from the mains in And the output terminal T that provides AC power to the load out . input t...
