<p>The invention relates to a high-voltage power supply to be connected by a network input (E1, E2, E3) to an alternating current network having a frequency Fr and n phases P1, P2,.. Pi,.. Pn, and providing, at least at one HV output, an output continuous high voltage (Vk1, Vk2, Vk3). The power supply includes a single-phase high-voltage conversion module Mi per phase Pi of the network having a current rectifying circuit (50) connected, by a single-phase input (Em) of the conversion module Mi, to a respective phase Pi of the network and, by a rectified current output (s1, s2), to a splitting circuit (51) having at least one splitting transistor (Trd) at a frequency Fd of said rectified current and p HV secondary circuits (S1, S2,...Sj,...Sp) each providing a secondary HV (Vc1, Vc2, Vcj,...Vcp), wherein p is an integer higher than or equal to 1 and j is the rank of the HV secondary circuit between 1 and p. A control and adjustment unit UC (60) of the power supply includes one control circuit CCMi per conversion module Mi. The invention can be used in the HV power supply of tube equipment such as power RF transmitters and progressive-wave microwave transmitters.</p> |
