How to Calculate and Solve for Half Bridge Output Voltage of Circuit under Strained Condition | Electrical Strain Guages

Last Updated on January 24, 2021

The image above represents half bridge output voltage of circuit under strained condition.

To compute for half bridge output voltage of circuit under strained condition, three essential parameters are needed and these parameters are Gauge Factor (GF), Strain (ε) and Input Supply Voltage (vi).

The formula for calculating half bridge output voltage of circuit under strained condition:

vo = (GF2) . ε vi

Where:

vo = Half Bridge Circuit Output Voltage
GF = Gauge Factor
ε = Strain
vi = Input Supply Voltage

Let’s solve an example;
Find the half bridge output voltage of circuit when the guage factor is 8, the strain is 4 and the input supply voltage is 2.

This implies that;

GF = Gauge Factor = 8
ε = Strain = 4
vi = Input Supply Voltage = 2

vo = (GF2) . ε vi
vo82 x 4 x 2
vo = 4 x 4 x 2
vo = 32

Therefore, the half bridge output voltage of circuit is 32 V.

Calculating for Guage Factor when the Half Bridge Output Voltage of Circuit, the Strain and the Input Supply Voltage is Given.

GF = vo x 2 / ε . vi

Where;

GF = Gauge Factor
vo = Half Bridge Circuit Output Voltage
ε = Strain
vi = Input Supply Voltage

Let’s solve an example;
Find the guage factor when the half bridge output voltage of circuit is 10, the strain is 15 and the input supply voltage is 18.

This implies that;

vo = Half Bridge Circuit Output Voltage =10
ε = Strain =  15
vi = Input Supply Voltage = 18

GF = vo x 2 / ε . vi
GF = 10 x 2 / 15 . 18
GF20 / 270
GF = 0.074

Therefore, the guage factor is 0.074.

Calculating for Strain when the Half Bridge Output Voltage of Circuit when the Guage Factor and the Input supply Voltage is Given.

ε = (vo x 2 / GF) / vi

Where;

ε = Strain
vo = Half Bridge Circuit Output Voltage
GF = Gauge Factor
vi = Input Supply Voltage

Let’s solve an example;
Find the strain when the Half Bridge Circuit Output Voltage is 10, the guage factor is 4 and the input supply voltage is 2.

This implies that;

vo = Half Bridge Circuit Output Voltage = 10
GF = Gauge Factor = 4
vi = Input Supply Voltage = 2

ε = (vo x 2 / GF) / vi
ε = (10 x 2 / 4) / 2
ε = (20 / 4) / 2
ε = 5 / 2
ε = 2.5

Therefore, the strain is 2.5.

Calculating for Input Supply Voltage when the Half Bridge Output Voltage of Circuit, Guage Factor  and Strain is Guage.

vi = (vo x 2 / GF) / ε

Where;

vi = Input Supply Voltage
vo = Half Bridge Circuit Output Voltage
GF = Gauge Factor
ε = Strain

Let’s solve an example;
Find the input supply voltage when the half bridge output voltage of circuit is 18, the guage factor is 10 and the strain is 7.

This implies that;

vo = Half Bridge Circuit Output Voltage = 18
GF = Gauge Factor = 10
ε = Strain = 7

vi = (vo x 2 / GF) / ε
vi = (18 x 2 / 10) / 7
vi = (36 / 10) / 7
vi3.6 / 7
vi = 0.514

Therefore, the input supply is 0.514.
