The present invention is related to a voltage conversion apparatus having a first loop circuit and a second loop circuit which share an inductance component, in which a current passes through the first and second loop circuits alternately in accordance with ON/OFF operation of a first switching element provided in the first loop circuit, characterized in that a direction of a magnetic field through the first loop circuit generated at the ON operation of the first switching element in the first loop circuit is the same as a direction of a magnetic field through the second loop circuit generated at the OFF operation of the first switching element in the first loop circuit subsequent to the ON operation.

Voltage conversion apparatus and electrical load driving apparatus to reduce noise through magnetic field

This onboard reception device includes: a first receiver; a second receiver which is tuned to a second frequency which is different from a first frequency to which the first receiver is tuned, and whose reception level is low; a noise cancellation means which cancels noise included in a first demodulated received signal which is demodulated by the first receiver, based upon a second demodulated received signal which is observed by the second receiver; and an output means which outputs the first demodulated received signal in which noise has been cancelled, in a manner in which it can be appreciated by a user.
