The inverter for low-power (SOHO) UPS systems is usually supplied from a 12 V or 24 V battery voltage, which is connected to the primary winding of a step-up transformer through either a push-pull or full-bridge (or H-bridge) converter. Higher battery voltages are used in higher power rated systems.
The different voltage conversion ratios of the inverters from cell G (b1G and b2G) caused them to have the highest power losses and hence the lowest efficiency. Figure 23. Comparison of buck DMSI efficiencies. Similarly, the different boost DMSIs were tested using the same parameters in Table 8 but at lower power (from 100 W to 1300 W).
The inverters presented in Refs. 9, 10, 11, 32, 34, 35, 38, 39, 40, 41, 42 are all single-stage non-microcontroller-based inverters that have a low voltage gain. Also, these inverters don’t take advantage from machine intelligence in their structure.
A high-voltage to low-voltage backup auxiliary power supply has become prevalent in automotive powertrain applications. This application report discusses key considerations and design guidelines for the backup power supply such as the operating voltage of the switching device, startup circuitry, noise coupling, and high-voltage isolation.
