To handle the low frequency oscillations of the three-phase four-wire inverter grid-connected system caused by small phase-locked range, slow locking speed and large steady-state error of the traditional phase-locked loop, an improved phase-locked lo

Simple, portable and low-cost experiments as RC and RL series circuits are proposed to experiment with DC circuits. Very common elements are used: a few electronics components (resistors, capacitors, coils and connecting wires) and two smartphones. W
