A voltage converter of a primary power supply voltage to the preset voltage of other level is proposed, the converter comprises an input smoothing filter, whose input is connected to the primary power supply, an output smoothing filter, whose output is connected to a load, and a control device. Moreover, it comprises at least two same invertors, whose inputs are connected to the output of input smoothing filter, and the outputs – via identical transformers to the inputs of two identical rectifiers, whose outputs are in series connected to the output of input smoothing filter and input of output smoothing filter. The pulses on invertors output have the same amplitude and pulse width and are time-shifted relative to the pulses of first inverter by 0.5(i - 1)/TK , where i – order of inverter, T- duration of rectifying interval, K – the total number of inverters. |
