Abstract

Supply circuits (1) for supplying loads (40) are provided with rectification circuits (20) comprising first AC terminals (2) for exchanging first AC signals with AC sources (50) and comprising second AC terminals (3) for exchanging second AC signals with the loads (40) and with protection circuits (30) for protecting the loads (40) against spikes. The protection circuits (30) comprise inputs (6) for receiving first DC signals from first DC terminals (4) of the rectification circuits (20) and comprise outputs (7) for providing second DC signals to second DC terminals (5) of the rectification circuits (20). These supply circuits (1) have relatively fast responses. The protection circuits (30) may comprise detector circuits (31) for detecting values of (parts of) the first DC signals crossing threshold values and limiter circuits (32) for, in response to detection results, limiting values of the second DC signals. The rectification circuits (20) may comprise four diodes (21-24).
