Title:
SIGNAL GENERATION CIRCUIT, VOLTAGE CONVERSION DEVICE AND COMPUTER PROGRAM
Document Type and Number:
Japanese Patent JP2017085424
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a signal generation circuit capable of making a minimum increment of a value to be set to a generation part for periodically generating a first signal having an ON time corresponding to the set value and a second signal of which the ON period does not overlap the first signal, substantially smaller than an actual increment with a relatively small processing load, a voltage conversion device and a computer program.SOLUTION: A CPU 11 identifies a setting Y first closest to and a setting Z second closest to a target value X at an interval of N cycles of a first signal that is generated by a generation part 16, determines N pieces of settings of the first signal from among Y and Z in accordance with a result of comparing magnitudes of the identified Y and Z with a magnitude of X, and sets the settings to the generation part 16 one by one at the interval of one cycle of the first signal. The CPU 11 calculates a value for setting an OFF time of a second signal in a first cycle of the N cycles as an addition value of a smaller settable value between settable values that are determined regarding the same N cycles, and a predetermined value and sets the calculated value to the generation part 16.SELECTED DRAWING: Figure 1
