P&O Algorithm is the most common algorithm for
tracking the maximum power from TEG module. This
algorithm tracks the maximum power by measuring the output
voltage and current from TEG module for calculating the
output power. If the change in power (ΔP) is positive it means
the operating point moves towards the maximum power point
voltage (VMPP) and stepping the operating voltage in same
direction. If the change in power is negative it means the
operating point moves away from the VMPP. After several
iterations the maximum power point (MPP) will be reached
