Boosting system, diagnosing method, and computer readable medium storing diagnosing program for diagnosing the boosting functions of a boosting section

A boosting system comprising:

• a boosting section that generates a boosted voltage obtained by boosting a first voltage in accordance with a second voltage outputted from a constant voltage circuit;
• and
• a comparison circuit, to which the boosted voltage, the first voltage, the second voltage and a ground potential are input,
• that compares a first difference value with a second difference value and that outputs results of comparison, wherein the first difference value is obtained from a difference between the boosted voltage and the first voltage, the second difference value is obtained from a difference between the second voltage and the ground potential,
• wherein the comparison circuit comprises:
• a single inverting amplifier;
• a first capacitor and a second capacitor that are connected in parallel, wherein an input of the single inverting amplifier is connected to the first capacitor and the second capacitor;
• a first switching element that connects the first capacitor and the boosting section such that the first voltage is inputted;
• a second switching element that connects the first capacitor and the boosting section such that the boosted voltage is inputted;
• a third switching element that connects the second capacitor and the boosting section such that the second voltage is inputted;
• a fourth switching element that connects the second capacitor to ground such that the ground potential is inputted;
• and
• a fifth switching element that short-circuits the input and an output of the single inverting amplifier.
