The main object of the present invention is to provide a multipath load drive circuit which can reduce loss and lower costs and can balance the current among a plurality of paths of loads. The multipath load drive circuit includes: a series branch X, a coupling capacitor, an input power source Vin, wherein the connection manner is that the series branch X consists of n rectification filter units in series according to the principle that all the rectification units can be forward-biased simultaneously, the series branch X has a head end, a tail end and (n - 1) series nodes which are referred to as XJ1, XJ2, ..., XJ (n - 1) successively, n being a natural number and being greater than or equal to 3, at least (n - 1) coupling capacitors are connected to the nodes XJ1, XJ2, ..., XJ (n - 1) respectively, the other end of the coupling capacitor to which the odd nodes are connected are connected to the input power source, and the other end of the coupling capacitor to which the even nodes are connected are connected to a common line of the multipath load drive circuit. |
