Abstract

A voltage compensation system (1, 1a) and an uninterruptible power supply (1, 1a) are provided. The voltage conversion device (3) selectively receives the first AC input source (AC1) or the second AC input source (AC2) through the first switching device (2), and converts the first AC input source (AC1) or the second AC input source (AC2) into a DC voltage (V1). The energy buffering device (8) is connected with the DC busbar (4). The energy buffering device (8) includes a bidirectional voltage conversion device (82) and an energy tank (81). One terminal of the bidirectional voltage conversion device (82) is connected with the DC busbar (4). The energy tank (81) is connected with the other terminal of the bidirectional voltage conversion device (82). During a dead time of the first switching device (2) switching between the first AC input source (AC1) and the second AC input source (AC2), the controller (9) controls the bidirectional voltage conversion device (82), so that the DC voltage (V1) is compensated by the energy tank (81).
