Two inverter power synthesis drag large-power lamp, and dilatation is reliable, but two self-oscillation chip oscillating voltage phase places should be consistent, unbalanced to eliminate non-linear intermodulation power, obtains stable output.To this end, introduce injection phase-locking to solve power combing Phase synchronization technology.
Injection phase-locking is without voltage-controlled tuning, phase discriminator, loop filter, and the simple superior performance of circuit, fringe cost is low.Injection phase-locking there substantially is not difference with looped phase locking, and simply structure is different with work process, is suitable to power combing large-power lamp stable oscillation stationary vibration frequency plot and synchronizes, stablizes output and avoid the too high power imbalances of device temperature rise, increase the service life.
Benchmark crystal oscillator quartz resonator quality factor are high, and frequency is minimum by variations in temperature, and highly stable to make reference accurate.Reference signal divided injection self-oscillation chip CTEnd locking phase.Unimplanted reference signal self-oscillation chip RC agitator produces free oscillation frequency, injects reference signal RC oscillating voltage and its Vector modulation, and by self-oscillation chip additive mixing locking phase, oscillator signal only has a fixing phase contrast with injecting reference signal.Synchronization bandwidth and injecting power direct ratio, with RC agitator loaded Q inverse ratio, owing to reference signal injects the input of RC agitator, gain is high, and small-power locks.The RC agitator of two self-oscillation chips connecting resistance R altogether3, electric capacity C5Synchronized oscillation, locking time is fast.
