When using a step-down DC-DC converter as an inverter, there are some limitations. The voltage difference between the input and the negative output must be less than the step-down DC-DC converter''s maximum operating input voltage. In essence, a step-down DC-DC converter with maximum input of 12V can be used to convert 5V to -7V, but not more.
When the output power is 200 W, the proposed inverter can achieve about 83% and 93% efficiency in the step-up mode and the step-down mode respectively. Table 3 illustrates the comparison result. As Table 3 shows, unlike the conventional inverter, the proposed inverter can provide not only stepped-up voltage but also stepped-down voltage.
Step-up and step-down converter and the motor inverter are merged into a single converter. Bidirectional and galvanically isolated energy transmission between battery and motor with reduced semiconductors number, easy control, and high efficiency are demonstrated.
Using a step-down converter as an inverting buck-boost converter is a valid application use case, supported by numerous reference designs and applications notes. The TPS82130 step-down power module is used as the example, because of its high integration level and simple design.
