Abstract: PROBLEM TO BE SOLVED: To provide a high power circuit which can prevent the damage or the performance deterioration of a device being the target of voltage application by shortening the rise time of power voltage at power ON.
SOLUTION: This power circuit has a voltage detecting circuit which detects power voltage and a PWM control circuit which controls the above detected output voltage to be constant by adjusting the pulse width of the row of output pulses, according to the detected voltage, and outputs the row of initial pulses of fixed pulse width for raising the power voltage within a specified time at power ON.

Abstract: PROBLEM TO BE SOLVED: To provide a temperature detector that has a thermostat or a thermistor directly attachable to a heating unit and can detect temperature of the heating unit in a simple structure. SOLUTION: This temperature detector includes a transformer, a thermostat that is directly attached to a conductive portion of a heating unit and has a contact point which is opened or closed corresponding to whether or not temperature of the heating unit becomes equal to or higher than predetermined temperature and is connected to a secondary coil of the transformer, and a DC voltage source and a transistor which are adapted to supply a required AC power to a primary coil of the transformer. The temperature detector further includes a current detecting resistor for detecting a current flowing in the primary coil of the transformer, and a comparator circuit that detects a voltage generated between both ends of the current detecting resistor due to the current flowing in the current detecting resistor and outputs an alarm signal when a level of the current flowing in the primary coil of the transformer exceeds a preset threshold.
