h1. Hardware
{{>toc}}
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.

h2. Measurement Block
* [[Measurement In the case of the single-phase projects, the specifications are described by the table below.
The Power Block Theory|Measurement 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 Theory Page]]

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.
