Abstract: |
An integrating device supplied by AC power in the condenser network. The characteristics are: it parallel connects a switch that opens as the sampling phase and closes as the integrating phase at the output end of the amplifier in the traditional integrating device of AC power supply switch; and meanwhile synchronize the integrating clock signals when the sampling and integrating phases of the amplifier and make the same width of the pulses of the AC power supply signal as the power input, and maintain the same state switching time and minimize the time when the low energy saving state in the sampling phase and when the normal working state in the integrating phase. Because it closes the amplifier in the sampling phase, so compared with the switch condenser network supplied by DC power it has the superiority of low power consumption. |
