The High-Reactance Autotransformer Ballast is used when the line voltage in insufficient to ignite the lamp using a reactor type ballast. As a result, these ballasts are bigger, heavier, and less efficient than reactor ballasts, but they can be used in a wide variety of applications, because they come with multitap capability.
The Reactor Electromagnetic HID Ballast is the simplest, smallest, most efficient and most economical type of electromagnetic ballast. The reactor ballast is electrically in series with the lamp. There is no capacitor involved with the operation of the lamp.
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.

The 2007 Ford Explorer Sport Trac Passenger Compartment Fuse Panel and Relay is located below the instrument panel on the driver’s side. If electrical components in the vehicle are not working, a fuse may have blown. Blown fuses are identified by a broken wire within the fuse. Check the appropriate fuses before replacing any electrical components. Always replace a fuse with one that has the specified amperage rating. Using a fuse with a higher amperage rating can cause severe wire damage and could start a fire. The following table and diagram shows detail fuse/relay function and location.
The 2007 Chevrolet Uplander has two fuse blocks, the instrument panel fuse block and the underhood fuse block. The instrument panel fuse block is located at the
right end of the instrument panel, on the passenger’s side of the vehicle. Open the front passegner’s door, and remove the cover, to access the fuse block. Following table outlines detail Fuse, Circuit Breaker and Relay table of 2007 Chevrolet Uplander.
The 2007 Mercury Mountaineer Passenger Compartment Fuse Panel is located below the instrument panel on the driver’s side. To remove a fuse use the fuse puller tool provided on the fuse panel box. If electrical components in the
vehicle are not working, a fuse may have blown. Blown fuses are identified by a broken wire within the fuse. Check the appropriate fuses before replacing any electrical components. Below table outlines detail Mountaineer Fuses Location and its related circuit protected.
