Uma metodologia de inversão ressonante da tensão na lâmpada é apresentada. O conversor integra o estágio de controle da potência e o estágio de inversão da tensão na lâmpada. A lâmpada é alimentada em baixa freqüência com forma de onda quadrada e simétrica, a fim de evitar a ocorrência do fenômeno da ressonância acústica. Um projeto detalhado do capacitor em paralelo com a lâmpada é desenvolvido, analisando parâmetros de estabilidade, ondulação de alta freqüência da potência na lâmpada e do tempo de inversão da tensão, a fim de evitar a re-ignição. Resultados experimentais são apresentados para validar a topologia proposta.

This work presents an integrated solution for Electronic Ballasts control of HPS lamps using the power lines as a transmission media. A message protocol will be implemented, with variables related to HPS lamps management. The protocol stack, including the Physical Layer, the Media Access Control Layer, the Network Layer and the Application Layer is designed focusing in the application purposed, i. e., energy management, light control and monitoring. A software application is designed so all units could be controlled and monitored remotely. Experimental results are presented in order to validate the integration between power lines and electronic ballasts to control HPS lamps.

The option for supply the lamp with this waveform is selected to avoid the acoustic resonance phenomenon occurrence. Conventionally, the electronic ballast to supply the lamp in this way should have three power stages: Power Factor Correction (PFC), Power or Current Control (PC) and inverter. The option, in this work, is to define a methodology in order to integrate this power stages, reducing the electronic ballast final cost, simplifying the circuit and providing a safe operation to the lamp. Seven different topologies are proposed and their experimental results are obtained in order to compare the advantages and disadvantages of each one.

The system is connected in parallel with the single-phase grid, that matches one of the output three-phase terminal. The converter absorbs active power from single phase grid to produce two additional phases of the three-phase system. Furthermore, it allows the voltage compensation or power factor correction through reactive power injection. This system also allows the connection of alternative sources to DC bus.

Research paper thumbnail of Modeling and control of an electronic ballast based on differential connection of Flyback converters

The electronic ballast supplies a 70 W high pressure sodium lamp with low frequency square waveform in order to avoid the acoustic resonance phenomenon. The modeling results in the transfer functions that relates the lamp voltage and current with the input voltage and switches duty cycle. A low cost microcontroller with fixed-point support was used to implement the digital control strategy. This strategy consists on a fast loop for current control and an outer slow power loop for maintaining the lamp power constant during its useful life. A prototype was implemented in order to verify the proposed controllers.
