  • Publication number: 20180248465
    Abstract: A CPU determines an ON-time setting value with which the generating unit generates a PWM signal having an ON time that is closest to the ON time corresponding to a product of a reference period and a target duty cycle, and sets the determined setting value in the generating unit. The CPU divides the ON time of the PWM signal based on the determined ON-time setting value, multiplies, by N, the period that corresponds to a result of the division, and specifies a period settable value with which a PWM signal having a period that is closest to a result of the multiplication is generated. The CPU determines period setting values for N periods based on a quotient and a remainder obtained by dividing the specified settable value by N, and sets the determined setting values in the generating unit for each period of the PWM signal.

    Abstract: Provided are a signal generating circuit, a voltage conversion device, and a signal generating method configured to make a minimum unit of values that are respectively set in m (where m is a natural number equal to or greater than 2) generating units that periodically generate PWM signals corresponding to the setting values substantially smaller than an actual minimum unit. A CPU specifies, at every n periods of the PWM signals generated by the m generating units SG1, SG2, . . . SGm, a settable value closest to the sum of target values for n periods, determines (m×n) setting values for n periods based on a quotient and a remainder obtained by dividing the specified settable value by the product of m and n, and sets the determined values in the respective generating units SG1, SG2, . . . SGm, using phase-specific interrupt processes that are different from each other.
