Hardware¶
- Table of contents
- Hardware
The hardware of the single-phase project consists of a 10cm by 10cm printed circuit board that hosts 5 electronics blocks.
These blocks all fulfill functions which are necessary to the proper operation of any power electronics converter.
Figure 1 illustrates these blocks.
Figure 1 - General overview of a power electronics converter
Each block is explained in detail in the sections below.
Power Block¶
To better explain the Power Block, this page splits its presentation in theory and practice.
Theory¶
The theory of the power block is explained in the page below.
Practice¶
In practice the power block is calculated to correspond to a certain set of specifications.
The specifications are given in detail in the page below.
In the case of the single-phase projects, the specifications are described by the table below.
The Power Block is implemented in a special page of the KiCad project available in the repository of the single-phase project.
Variable | Description | Value |
---|---|---|
Vlow | Maximum low-side voltage | 60 V |
Vhigi | Maximum high-side voltage | 120 V |
freq | Switching frequency | 100 kHz |
Pnom | Nominal power rating | 500 W |
With these specifications, the single-phase converter uses the following components on it Power Block
Component | Description | Reference | RS Ref. |
---|---|---|---|
ML1 | Low-side MOSFET transistor | FDPF39N20 | - |
MH1 | High-side MOSFET transistor | FDPF39N20 | - |
CPL1-4 | Low-side Capacitors | - | - |
CPH1-4 | High-side Capacitors | - | - |
L1 | Power Inductor | 1410478C | - |
DL1 | Low-side Schottky Diodes | MBR20200 | - |
DH1 | High-side Schottky Diodes | MBR20200 | - |
The MOSFET and the Schottky diodes were chosen for their voltage rating (200V) and their current rating (30A - to be confirmed).
The Capacitors were chosen for their voltage rating, 160V - to be confirmed.
The Inductor was chosen for its current rating of 10 A.
