Abstract
An induction coil driver card for a railroad switch consists of a main power supply, a control unit, at least one induction heating unit, and an interface driver. The main power supply is electrically connected to the at least one induction heating unit that is used to generate eddy current fields. The generated eddy current field excites the atoms within the railroad switch resulting in elevated temperatures. The power input to the induction heating unit is managed via the control unit. The interface driver allows the user to control the frequency ranges received by the induction heating unit by utilizing the control unit. The interface driver also allows the user to have remote access via a wireless cellular modem.
