Abstract

The invention provides an intelligent dual-power electronic fast converter and a conversion method, and relates to the technical field of power supply equipment. The converter comprises an intelligent control conversion part composed of two three-phase bridge circuits, two limit voltage circuits, phase sequence and open phase detection circuits of a common power supply and a standby power supply, and a logic conversion circuit. A mechanical and electrical execution part consists of a Schmitt trigger, a power electronic device and a solid-state relay; phase sequence and open-phase detection is performed on the three-phase voltage signal of the frequently-used power supply or the standby power supply; when the input of the frequently-used power supply is open-phase, one path of output of the logic conversion circuit starts a solid-state relay through 5V electricity and is connected to a starting coil of an alternating-current load; the other path of output enters the Schmitt trigger, and a 5-volt 4-millisecond square wave signal is output by a monostable oscillator and is sent to a power electronic device to be connected with a load; and when the alternating current contactor is completely connected with the alternating current of the standby power supply, the power electronic device is disconnected from the standby power supply to form quick conversion of the dual power supplies.

Description

technical field

[0001] The invention relates to the technical field of power supply equipment, in particular to an intelligent dual-power electronic fast converter and a conversion method. Background technique

[0002] Intelligent dual power electronic fast converter, commonly known as dual power (common and standby) transfer switch, can be widely used in the field of AC power supply and needs backup power conversion, especially for occasions where instantaneous power failure is not allowed, the two-way power supply on electrical equipment. It can be applied to electrical equipment in industries such as electric power, petroleum, chemical industry, metallurgy, mining, coal, marine ships, and various factories and enterprises. At the same time, it can also be used in special industries such as military facilities and equipment, railway signals, bank data transmission, emergency operating rooms, high-speed data transmission, and high-speed elevators.
