The diagram in Figure 2 shows a static bypass switch connected across a UPS. The UPS. could be a double conversion or a delta conversion or rotary type. The static bypass switch. provides a means to accomplish high-speed transfer to the bypass path in case of UPS.
A standby UPS runs the computer off of the normal utility power until it detects a problem. At that point, it very quickly (in five milliseconds or less) turns on a power inverter and runs the computer off of the UPS's battery (see How Batteries Work for more information).ou could fairly easily build a continuous UPS yourself with a largish battery charger, a battery and a power inverter. The battery charger continuously produces DC power, which the inverter continuously turns back into 120-volt AC power.
