 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.

 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.

 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.
