Abstract: The solid-state imaging element includes a photoelectric converter, a first separator, and a second separator. The photoelectric converter is configured to perform photoelectric conversion of incident light. The first separator configured to separate the photoelectric converter is formed in a first trench formed from a first surface side. The second separator configured to separate the photoelectric converter is formed in a second trench formed from a second surface side facing a first surface. The present technology is applicable to an individual imaging element mounted on, e.g., a camera and configured to acquire an image of an object.

Abstract: A power converter capable of minimizing the amount of fluctuation in the input power value to the boost circuit when changing the number of operating circuits and the switching frequency; when reducing the number of boost chopper circuits operating and the switching frequency the controller reduces the duty cycle of the PWM signal to a circuit to be halted while said circuit scheduled for halt operates, whereafter the controller halts operation of said circuit scheduled for halt and changes the switching frequency to a frequency corresponding to the state determination value.

Abstract: As having a charge/discharge control function of storage batteries, when a plurality of power conditioners having a same basic switching period are installed together, hunting of charging/discharging power of the storage battery connected to each power conditioner is suppressed. Execution periods of control processes performed by control units 14 of a plurality of power conditioners 10 that have a function of controlling charging and discharging of storage batteries 25 are changed from basic switching periods so as to be different from each other.
