Title:
SIGNAL GENERATION CIRCUIT AND VOLTAGE CONVERSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/126493
Kind Code:
A1
Abstract:
In the present invention, a signal generation circuit and a voltage conversion apparatus, which output PWM signals to a plurality of objects to be driven on the basis of set target values, are achieved by having a configuration in which the minimum unit of a duty can essentially be set to be less than a predetermined settable value and concentration of heat generation spots can be suppressed. In a signal generation circuit (1), a determination unit determines, when the target values satisfy a prescribed condition, a combination of duties of the PWM signals to be outputted to the objects to be driven, by using a combination of a variety of settable values on the basis of the target values. An allocation unit allocates, each time a combination is determined by the determination unit, the settable values for the determined combination to the objects to be driven, and changes the allocation priority order according to the lapse of time.
