Patent ID: 8519754

Claim:
A system for signal synchronization, the system comprising: a first selection component configured to receive a first mode signal and generate a first selection signal based on at least information associated with the first mode signal, the first selection signal indicating a first operation mode; a first signal generator configured to, if the first selection signal satisfies one or more first conditions, receive a first input signal and generate at least a first clock signal based on at least information associated with the first input signal, the first input signal including a first input rising edge and being associated with a first input frequency, the first clock signal including a first clock rising edge and being associated with a first clock frequency; a second signal generator configured to, if the first selection signal satisfies one or more second conditions, generate at least a second clock signal, the second clock signal including a second clock rising edge and being associated with a second clock frequency; and a first gate drive component configured to: if the first selection signal satisfies the one or more first conditions, receive at least the first clock signal and output a first drive signal to a first switch based on at least information associated with the first clock signal; and if the first selection signal satisfies the one or more second conditions, receive at least the second clock signal and output a second drive signal to the first switch based on at least information associated with the second clock signal; wherein: the first input frequency and the first clock frequency are the same; the first input rising edge and the first clock rising edge both correspond to a first time; and the one or more second conditions are different from the one or more first conditions.
