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. p=. {{thumbnail(theory_power_converter_1.png, size=350, title=Theoretical view of a power electronics converter)}} Each block is explained in detail in the sections below. h2. Power Block The Power Block is the part that manages input/output power within the board. It consists of a single inverter leg, as illustrated in the figure below. p=. {{thumbnail(single_phase_topology.png, size=350, title=The power topology of the single-phase board)}} This topology allows the control of the current in the inductor L by controlling its charge and discharge using the switches. The figure below shows the switching and the current flow within the inductor. p=. {{thumbnail(states_converter_1.png, size=700, size=500, title=Current flow during switching)}} The switching leads to an average current flow between its input and output as shown in the image below. p=. {{thumbnail(switching_states_1.png, size=700, title=Current flow during switching)}} h2.
