Free QuoteAC Uninterruptible Power Supply (UPS) systems cover a wide range of power, from single-phase systems rated at less than 1 kVA to three-phase systems rated at over 1000 kVA.
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.
Typical current and voltage control loops for UPS inverter. In SPWM control technique, the output voltage feedback is compared with a sine reference signal, and the error voltage is compensated by a PI regulator to produce the current reference. The current through the inductor or the capacitor is sensed and compared with the reference signal.
Generally, the tasks of output voltage control for UPS inverters are providing fast dynamic responses and maintaining a perfect sinuso-idal voltage waveform even with nonlinear or changing loads. To achieve these aims, many controllers have been proposed in the literature.
It is well known that the main control objective in an UPS inverter is the tracking of the delivered voltage towards a desired sinusoidal reference in spite of the presence of distorted loads, . UPS systems can be classified as static, rotary and hybrid.
It consists of an AC/DC converter, a battery bank, a DC/AC inverter, and a static switch. A passive low-pass filter may also be used at the output of the UPS or inverter to remove the switching frequency from the output voltage. The static switch is on during the normal mode of operation.
