    摘要: The present invention relates to a tri-state delay-typed phase lock loop, which comprises: a phase and frequency detector, a mode detector, a mode selector, a first sampling delay unit, a plurality of counters, a second sampling delay unit, and a phase and frequency calculator. The phase and frequency of the input reference signal can be determined automatically by the phase lock loop, and the output synchronization signal can be generated such that the frequency and the phase of the output synchronization signal are identical to those of the input reference signal.

    摘要: A DC-AC converter is provided. The DC-AC converter includes a time-varying DC power generating circuit, an AC power generating circuit and a transmission capacitor. The time-varying DC power generating circuit is controlled by a pulse width modulation (PWM) signal to transform a DC source into a time-varying DC power. With reference to the time-varying DC power, the AC power generating circuit is controlled by a first polarity switching and a second polarity switching signal to generate an AC power. The transmission capacitor, coupled to the time-varying DC power generating circuit and the AC power generating circuit, transmits the time-varying DC power from the time-varying DC generating circuit to the AC power generating circuit.
