It utilizes a low power uninterruptible power supply (UPS) for digital clocks and home appliances, such as VCRs and microwave ovens, which contain ... Without a dc-dc converter, the peak value of the AC output voltage of the UPS also decreases with the decaying capacitor voltage. ... A block diagram of the low power UPS is shown in Figure 1. ... The 120V:12.6V transformer supplies power to the charging circuit, which maintains the voltage of the capacitor bank at the proper level.
