摘要:
A motor control device that detects a motor current through ΔΣ AD conversion includes a stop signal generator and a stop signal controller. When a difference between a maximum value and a minimum value of three phase voltage command values to be applied to a motor is smaller than or equal to a predetermined threshold, a stop signal that causes the ΔΣ AD conversion to stop is output with a delay by the time corresponding to a delay in current detection while a leakage current caused by on and off of a power conversion element is occurring.

An illumination apparatus includes a light-emitting element, a first lens, and a second lens. The first lens faces the light-emitting element, and has a radiation port from which a light beam is radiated, a first incident surface, a second incident surface, a first reflection surface, and a second reflection surface. The second lens faces the radiation port. The first incident surface faces the light-emitting element, and guides a light beam from the light-emitting element to the radiation port. The second incident surface guides a light beam not passing through the first incident surface to a direction toward the outer periphery of the first lens. The first reflection surface reflects a light beam from the second incident surface to guide the light beam to the radiation port. The second reflection surface reflects a light beam passing through the first incident surface and then deviating from the direction toward the radiation port, and a light beam reflected on the first reflection surface and then deviating from a direction toward the radiation port, to guide these light beams to the radiation port.

Power feed device (100) supplies power to storage battery (152) mounted on vehicle (150), through power receiving unit (154) of vehicle (150). Power supply unit (104) performs preliminary supply to power receiving unit (154) while sequentially changing a frequency, and performs main supply with power larger than in the preliminary supply. Power supply-side controller (103) acquires frequency characteristics associated with power supply coil (104a), and specifies a resonance frequency based on the acquired frequency characteristics. Power supply-side controller (103) determines whether or not to supply power to power reception coil (154a) based on a frequency difference between resonance frequencies.
