Design and Analysis of High-Voltage Transformer for HID Lamp Igniter
... In HV or Pulse transformer applications, the key issue is to prevent the core saturation. There are two main types for saturation: volt-sec saturation and NI value limitation. Because the ballast tries to ignite the lamp more than once for reliability, the HV transformer should be designed not to sa ...
