Pulse width modulation
–
calculation
W
ith pul
se width modulation, control is implemented by a variable mark-space ratio.
During the time t
ON
the valve is opened and during the time t
OFF
it is closed.
On account of t
ON
= 0.4 x
t
CYC
the valve is set to about 40 % on. t
CYC
is the so-called PWM cycle time for
continuous control.
