FIELD: radio engineering.
SUBSTANCE: invention refers to pulse work and can be used in pulse width converter control systems. Technique is characterised by that sequence of modulation period is specified. Reference signal is extended within each modulation period. Control signal within modulation period is compared to reference signal. Output pulse is formed within each modulation period during difference constant-sign interval of reference signal and average value of control signal for which pass band is specified ΔSy = (Umax-Umin) of maximum allowed value Umax to minimum allowed value Umin. Reference signal is compared either to instantaneous control signal if the latter are within specified pass band ΔSy, or to average control signal if instantaneous values of the latter falls beyond specified pass band ΔSy.
EFFECT: higher noise immunity and processing speed.
