Abstract: A full bridge inverter is provided to improve flexibility by connecting two drivers with a full bridge inverter circuit to match with a push/pull control chip for control. A full bridge inverter includes a push/pull control chip(103), a first switch(Q6), a first SCR switch(Q5), a first N-MOS(Q1), a second N-MOS(Q2), a second switch(Q8), a second SCR switch(Q7), a third N-MOS(Q3), and a fourth N-MOS(Q4). The push/pull control chip(103) has a first output terminal(A) and a second output terminal(B) which individually output a first control signal and a second control signal with a duty cycle below 50%. The first switch(Q6) is coupled at the first output terminal(A) of the push/pull control chip(103). The first SCR switch(Q5) has a gate coupled at the first switch(Q6), and an anode coupled at DC power. The first N-MOS(Q1) has a gate coupled at a cathode of the first SCR switch(Q5), a drain coupled at the DC power, and a source coupled at one terminal of a primary side of a transformer(T2). The second N-MOS(Q2) has a gate coupled at the first output terminal(A) of the push/pull control chip(103) through a first buffer circuit(302), a drain coupled at the source of the first N-MOS(Q1), and a source coupled at a reference terminal. The second switch(Q8) is coupled at the second output terminal(B) of the push/pull control chip(103). The second SCR switch(Q7) has a gate coupled at the second switch(Q8), and an anode coupled at the DC power. The third N-MOS(Q3) has a gate coupled at a cathode of the second SCR switch(Q7), a drain coupled at the DC power, and a source coupled at the other terminal of the primary side of the transformer(T2). The fourth N-MOS(Q4) has a gate coupled at the second output terminal(B) of the push/pull control chip(103) through a second buffer circuit(322), a drain coupled at the source of the third N-MOS(Q3), and a source coupled at the reference terminal.
