A phase frequency detector compares a reference clock signal to a feedback clock signal to generate pulses in one or more output signals. The one or more output signals have a minimum pulse width. The phase frequency detector has a temperature sensing circuit. The phase frequency detector adjust...
include using an internal clock configured to operate at quadruple the switching frequency of the pulse width modulation signal, and the periodic set signal may have a pulse width of about 25 percent of the period of the PWM switching frequency. The minimum pulse width of the PWM output signal...
for supplying a pulse pattern to semiconductor devices of a power converter (such as an inverter or a converter) using the pulse width control scheme is provided with function of dropping pulses so that the pulse pattern may form a predetermined function provided that the pulse width is shorter...
