China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

High starting voltage of the electronic ballasts comprising: a converter, the converter having a switching circuit  in response to the switching control signal and operatively connected to the DC bus; DC controller, its perception of the DC bus voltage signal with a reference DC bus voltage signal is compared to the switching control signal; start the regulator, which is operatively connected to the DC controller in order to start when the predetermined time.at least one of the adjusted within perception of the DC bus voltage signal with a reference DC bus voltage signal to start the DC bus voltage is greater than the steady-state DC bus voltage.
