1-Φ Half Bridge Inverters
1-Φ bridge inverter may be of two type 1-? half bridge and 1-? full bridge inverter. 1-? half bridge inverter with resistive load to explain the principle of inverter.
The thyrisotrs T1 T2 will conduct for the duration till its gate pulse i g1 and ig2 are present respectively and as the pulses are removed thyristor will get turned off. When the applied to T1 current if flows through peer supply T1 and Ri. The output voltage V0 = Ddc/ 2 is obtained. As the igl is removed and ig2 is applied to T2 thyristor T1 gets timed off and load current i0 flows through lower battery or lower supply, RL and T2 hence the output voltage is reversed so V0 = Vdc/2 is obtain das shown .
Here the voltage and current wave forms will remain in same phase due to resistive load. In case when other than resistive load is i0 will not be in phase with v in this condition diodes will allow the current to flow when main thyristor get turned off. Therefore these diodes are known as feedback diodes.
(a) A second order Sallen and Key Low Pass Active Filter has these component values R 1 =R 2 =15 kΩ, C 1 =C 2 =1 nF and the feedback resistors are R 3 =3.9 kΩ and R 4 =2.3 kΩ
