Abstract:
An inverter circuit comprising:a synch signal source having a first frequency and a first phase;a first voltage source inverter circuit coupled to a load and said synch signal source, said first voltage source inverter circuit comprising a cycle time counter generating a first cyclic output signal, a first sampling circuit receiving said first cyclic output signal and sampling said first cyclic output signal, said first sampling circuit generating a magnitude signal and a first phase signal in response to said first cyclic output signal;a second voltage source inverter circuit coupled to said load in parallel with said first voltage source circuit, said second voltage source inverter circuit coupled to said synch signal source, said second voltage source inverter circuit comprising a second cycle time counter generating a second cyclic output signal, a second sampling circuit receiving said second cyclic output signal and sampling said cyclic output signal, said second sampling circuit generating a magnitude signal and a second phase signal corresponding to said second cyclic output signal, said second phase signal having a phase substantially similar to said first output signal.
