Connecting power supplies in parallel is commonly used to increase the available output power or to provide system redundancy in the event of a power supply failure. The correct and reliable way to connect two or more power supplies in parallel is to have them equally share the load current.
Conversely, connecting power supplies in series ensures that each supply provides the necessary load current, resulting in the load receiving a combined output voltage from the series-connected supplies.
Nonetheless, it is feasible to parallelize supplies with matching output voltages while having non-matching maximum output currents. Power supplies A and B must maintain identical output voltages, while their maximum output currents can differ. The voltage across the load matches the voltage provided by the power supplies.
Typically, identical supplies are used when configuring them in parallel, given the challenges associated with efficiently aligning different power supply configurations. Nonetheless, it is feasible to parallelize supplies with matching output voltages while having non-matching maximum output currents.
As mentioned previously, when connecting the outputs of supplies in parallel, each supply provides the required voltage, and the load current is shared between the supplies.
In contrast, when power supplies are connected in parallel, each supply contributes the required voltage while the load current is shared among them.
