一、电源电路工作原理分析松下NV-M7摄像机电源原理图如图1所示。电源部分采用了直流变换电路,用12V充电电池供电,它分别输出5V、9V、12V、16V和8V电压。12V电压由适配器或蓄电池盒送来的直流电压经接插件P1001、P1003进入电源部分。电源电路由变换器专用集成块IC_(1001)(BA6149LS)、脉冲控制放大集成块IC_(1002)(UN102)和运放集成块I_C(1003)(AN6562S)、IC_(1004)(AN6914S)、DC-AC变换管Q_(1003)(2SD1293M)
First, the working principle of the power circuit Panasonic NV-M7 camera power schematic shown in Figure 1. Power supply part of the DC converter circuit, with 12V rechargeable battery-powered, which were the output 5V, 9V, 12V, 16V and 8V voltage. 12V voltage from the adapter or battery box DC voltage sent through the connector P1001, P1003 into the power section. The power supply circuit is composed of converter-specific integrated circuit IC_ (1001) (BA6149LS), pulse control amplification IC_ (1002) (UN102) and op amp IC I_C (1003) (AN6562S), IC_ (1004) -AC change tube Q_ (1003) (2SD1293M)
