Burner ignition controller and improved coil bobbin

An igniter operable to provide a high voltage arc for igniting a fuel-air mix in the burner, the igniter comprising:

• a primary supply input to receive electrical power for the igniter;
• a switching circuit comprising one or more switching components;
• and a high voltage switching transformer, comprising:
• an igniter bobbin comprising a coil bobbin and a pair of high voltage insulators extending therefrom made of the same material to form one piece, resulting in a single monolithic structure;
• primary and secondary coils of wire wound onto the igniter bobbin, the coils comprising a high voltage secondary coil of wire and one or more low voltage secondary coils of wire;
• a pair of high voltage electrodes connected to the high voltage secondary coil of wire and held within the high voltage insulators of the igniter bobbin;
• and a segmented core operably coupled to the igniter bobbin configured to provide mutual inductive coupling between the primary and secondary coils of the igniter bobbin;
• wherein the primary coil of the high voltage switching transformer is alternately switched between voltages received at the primary supply input to induce a high voltage at the secondary coil and produce an arc between the pair of high voltage electrodes for igniting the fuel-air mix in the burner.
