Electronic ballast simulation circuit start-up method for fluorescent lamp

Abstract

The invention discloses a startup method for a simulating circuit of electronic ballasts used for fluorescent lights. In a simulation software circuit window, the DC power supply circuit in the electronic ballast circuit is replaced by a pulse power supply, i. e. the input end of the auto-simulated oscillated circuit is connected with the output end of the pulse power supply. So the self-simulated oscillation circuit has a disturbance voltage in the initial input status, parameters of the pulse power supply is set in the simulation interface of Multisim multisim circuit simulation software, and the circuit simulation software is run when parameters of other elements in the circuit are set and instruments are added into the circuit; The pulse power supply as the DC power supply output instead of an electronic ballast solves the problem that initial status of the input end of the self-simulated oscillated circuit of the ballast circuit has no initial disturbance and increment, and the circuit simulation software can carry out operation startup computation for the fluorescence through the electronic ballast simulation circuit for convenience of engineering and technology personnel to carry out circuit performance analysis and optimization design.

AI Technical Summary

Problems solved by technology

However, in the simulation process, especially some closed-loop positive feedback circuits including multi-winding nonlinear transformers; circuits such as self-excited oscillators, circuits that require self-triggering, and electronic ballasts for fluorescent lamps belong to such circuits. The software Unable to simulate, the specific performance is that the simulation software does not run, and there is no response or prompt

The fundamental reason is that the initial state of the circuit is in a stable state, without initial disturbances and increments, so the software cannot perform calculations
