Problems solved by technology

In a system in which a plurality of high-voltage drive devices are connected to each other, for example, when changing the resonance frequency by changing the capacity of a reactor or a capacitor, it is necessary to add new electronic components, which causes a problem of complicating the system
In addition, when the number of high-voltage drive devices mounted on an electric vehicle increases, it may be difficult to adjust the frequency so as to avoid overlapping of frequency bands among the devices.

Abstract

Provided is a power transmission / reception system capable of suppressing an increase in resonance current while suppressing the complexity of the system configuration. The power transmission / receptionsystem is provided with: a power supply; at least one first device that charges and discharges power to and from a power source; at least one second device of charging or discharging power only to the power source; and a diode that is provided in a power line that connects the power source to the first device and the second device, and that restricts the transmission and reception of power between the power source and the second device to a single direction.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2018-146191 for which it applied on August 2, 2018, and uses the content here. technical field [0002] The invention relates to a power receiving and receiving system. Background technique [0003] Conventionally, an electric vehicle including a plurality of high-voltage drive devices such as a storage battery, a charger, a DC / DC converter, a power conversion module, and a compressor for an air conditioner is known (for example, refer to Japanese Patent Laid-Open No. 2013-115957) . In this electric vehicle, for example, current resonance between the power conversion module and the air conditioner compressor is suppressed by making the frequency of the power conversion module (for example, switching frequency) different from the frequency of the air conditioner compressor (for example, LC resonance frequency). [0004] However, in the above-mentioned conventional electric vehicle, it is desired...
