Power conditioner device and module substrate structure using the same

Abstract

The invention relates to a power conditioner device. This invention enhances the maintenance when the individual electronic component fails and realizes low cost maintenance. When raising the DC power supplied from a solar cell or a fuel cell by means of a DC / DC converter circuit (30) and converting to the AC power by means of an inverter circuit (40), an electronic circuit such as the DC / DC converter circuit (30) and the inverter circuit (40) or a CPU for controlling the operation of the circuits are accommodated in a case body to supply the AC power to a general load, the DC / DC converter circuit (30) and the inverter circuit (40) are mounted on a DC / DC converter circuit mounting substrate (31) and an inverter circuit mounting substrate (41), which are configured as separate bodies, for modularization.

Description

technical field [0001] The present invention relates to a power conditioner for boosting direct current supplied from solar cells, fuel cells, etc., and converting it to alternating current, and supplying the alternating current to general loads, and to a module substrate structure used in the device. Background technique [0002] This type of power conditioner consists of a DC / DC converter circuit that boosts the DC power supplied from solar cells, fuel cells, etc., and a reactor that rectifies the DC power supplied from the DC / DC converter circuit and converts it into AC power. An inverter circuit, or a CPU that controls these DC / DC converter circuits and the inverter circuit are configured. [0003] Furthermore, similar to the CPU, etc., the DC / DC converter circuit and the inverter circuit are composed of a large number of electronic components such as switching elements and diodes. In the conventional technology, these electronic components such as switching elements, di...

Problems solved by technology

[0005] However, in such a power conditioner, since each electronic component is mounted on a single printed circuit board, it is very difficult to replace the failed electronic component and perform maintenance when each electronic component fails individually. It is necessary to replace the new printed circuit boards with all the new electronic parts installed, and discard the old printed circuit boards that have not been equipped with normal electronic parts, which will increase maintenance costs and may have an impact on the global environment

[0006] In addition, since the inverter circuit and the DC / DC converter circuit are constructed using switching elements, they generate extremely high temperatures, which may affect the operation of the CPU, etc.
