PROBLEM TO BE SOLVED: To reduce a DC through the primary winding wire of high voltage generation transformer and to reduce the rise of temperature on the primary winding wire of high voltage generation transformer by providing a cholk coil parallelly connected to the serial connection between the primary winding wire of high voltage generation transformer and a resistor. SOLUTION: A cholk coil 2 is parallelly connected to the primary side winding wire of high voltage generation transformer 1 so that the DC can be branched to the cholk coil 2 and the primary side winding wire of high voltage generation transformer 1. The DC is branched while making its branch rate inversely proportional to the valid resistance value between the cholk coil 2 and the primary side winding wire of high voltage generation transformer 1. Namely, the less the valid resistance value is reduced, the higher the DC is distributed. Then, a resistor 3 is further added so that the value of resistor 3 is selected for letting most of DC flow through the cholk coil 2. By selecting that resistance value like this, no DC flows through the primary side winding wire of high voltage generation transformer 1. |
