Single-phase half-bridge inverter


Operational Details

Consists of 2 choppers, 3-wire DC source
Transistors switched on and off alternately
Need to isolate the gate signal for Q1 (upper device)
Each provides opposite polarity of Vs/2 across the load

DC Supply Current
If the inverter is lossless, average power absorbed by the load equals the average power supplied by the dc source.
For an inductive load, the current is approximately sinusoidal and the fundamental component of the o ....etc

INTRODUCTION
Efficient control of D.C motor speed is very economical to any industries for that reason we are using full wave rectifier in which we are using triacs as switches because of bi-directional nature of triacs we are preferred instead of using thyrister as a switches. To obtain a four quadrant operation we need 8 switches if we use thyristers (this circuit called dual converter) and if we use triacs we need 4 switches only.

Abstract
This paper proposes a feed-forward control in a halfbridgeresonant dc page link inverter. The configuration of feed-forwardcontrol is based on synchronous sigma-delta modulation and the halfbridgeresonant dc page link inverter consists of two inductors, onecapacitor and two power switches. The simulation results show theproposed technique can reject non-ideal dc bus improving the totalharmonic distortion.
Keywords—Feed-forward control, Resonant dc page link inverter,Synchronous sigma-delta modulation.

The Half Adder & Full Adder
The Half Adder
Adds two binary digits
Produces a sum bit(S) and a carry bit(C)
Carry C is the AND of A and B
ie,C=AB
Sum is the X-OR of A and B
ie,S=AB+AB
The Full Adder
Adds two bits and a carry input
Outputs a sum bit and a carry
Adds the bit A&B and carry frm previous column(carry in)
