Hid Ballast Schematic - High intensity discharge (HID) lighting, by definition, has high levels of electrical discharge, to create an electrical arc in the bulb, which emits light. The main controller circuit of the ballast has two main functions: it inverts the power into an AC signal, and controls the voltage output as the bulb operates. Good, quality HID. Automotive Headlamp HID Ballast Reference Design The automotive HID ballast adopts an ignition circuit, which is driven by a dual-frequency inverter, as shown in Figure 7(B). Compared to a conventional ignition circuit with a voltage doubler, which is shown in. The wiring diagram is the blueprint for the ballast circuitry, including the input supply voltage and grounding methods. A ground connection must be made to all ballasts to avoid shock hazard, personal injury or damage to the luminaire or installation..

HID ballasts are classified by the type of circuit they use: Reactor (R), High Reactance Autotransformer (HX), Constant wattage Autotransformer (CWA), Magnetic Regulator, or Electronic. HID Ballasts are typically classified as High Power Factor (HPF) or Normal Power Factor (NPF).. An electrical ballast is a device placed in line with the load to limit the amount of current in an electrical circuit. It may be a fixed or variable resistor. It may be a fixed or variable resistor.. 70 W HID lamp ballast based on the L6569, L6385E and L6562A Introduction The inverter is realized by a full bridge driver with a power control circuit. The booster converter for power factor correction (PFC) is controlled by the L6562A controller (U1). The inverter is a full bridge topology driven by two pairs of half bridge buck.
