The following file contains detail information about HID Lamps and Ballast Circuit Diagram, available input voltage, maximum input current, power factor, regulation, input watts loss, crest factor. and ballast test (Short-Circuit Current Test, HID Ballast Continuity Testing and Open-Short Circuit Test Limits).
Magnetically Regulated (Mag Reg) and Regulated Lag (Reg Lag) are another type of EM (Electromagnetic Ballasts) HID ballasts. This ballast design is the most sophisticated and provides the highest power regulation to the lamp. They utilize a magnetic with three separate coils. The following schematic shows the Magnetic Regulator (Regulated Lag) HID Ballast Circuit Diagram. This circuit can operate at a variety of line voltages by usingthe different Line V transformer tap locations.
Also known as lead style ballasts, Constant-Wattage Autotransformer (CWA) ballasts are the most common ballasts used on 175 W or higher MH lamps. It offers the best compromise between cost and performance, means of providing stabilized light output (lamp regulation) as opposed to the Magnetically Regulated circuit. The circuit consists of a high reactance autotransformer with a capacitor in series with the lamp resulting in a high power factor ballast. Shows a typical Constant-Wattage Autotransformer (CWA) HID Ballast Circuit Diagram. This circuit requires an ignitor for QMH (Quartz Metal Halide) pulse start, CHM (Ceramic Metal Halide) and HPS (High Pressure Sodium).
The following file is an application note from st.com describing the two stages of electronic ballast for a 250 W HID metal halide lamp. The components include a PFC driver, half-bridge drivers, a microcontroller, an auxiliary power supply, a voltage reference, logic parts, an amplifier, comparators, power devices as Power MOSFETs, IGBTs, and fast diodes.
