Abstract

The invention relates to a portable multifunctional alternating current power source. The portable multifunctional alternating current power source comprises a storage battery, a direct current input filter circuit, a preceding stage inverter circuit, a high-frequency transformer, a rectification filter circuit, a back stage inverter circuit and an alternating current output filter circuit, all of which are connected in sequence. A current and voltage detecting circuit detects and feeds the current output current and the current output voltage back to a DSP chip, the DSP chip is connected with the preceding stage inverter circuit through a preceding stage inversion drive circuit and controls the preceding stage inverter circuit to carry out inversion, and the DSP chip is connected with the back stage inverter circuit through a back stage inversion drive circuit. The DSP chip controls the back stage inverter circuit to provide 57.7-volt single phase alternating current voltage, 100-volt single phase alternating current voltage and 220-volt single phase alternating current voltage. The portable multifunctional alternating current power source is convenient to carry, low in cost and stable and reliable in running.

Description

technical field [0001] The invention relates to a mobile power supply, in particular to a portable multifunctional AC power supply. Background technique [0002] In the current power supply system, once the system fails, when the electricity customer requests emergency repair, the electric energy meter is often not available or very inconvenient to use because of the on-site power outage, making it difficult to meet the customer's demand for electricity on the spot. Nowadays, the battery technology has been perfected. It is not only convenient but also portable. Inverting the DC power provided by the battery into an AC power with a suitable voltage level to supply the energy meter can effectively solve the above contradictions and improve work efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a portable multifunctional AC power supply that can provide multiple voltage levels in order to overcome the abo...
