Abstract:
1. A rectifier comprising: (a) AC input lines at which AC power is received by the rectifier and DC output terminals at which DC power is provided by the rectifier; (b) a first half-controlled bridge rectifier having an AC input and a DC output connected to the DC output terminals, the first half-controlled bridge rectifier having a full bridge of diodes connected between the AC input and DC output and controllable switching devices connected in parallel with half of the diodes in the bridge; (c) a second half-controlled bridge rectifier having an AC input and a DC output connected to the DC output terminals to provide DC power thereto in parallel with the first half-controlled bridge rectifier, the second half-controlled bridge rectifier having a full bridge of diodes connected between the AC input and the DC output and controllable switching devices connected in parallel with half of the diodes in the bridge; (d) inductances connected between the AC input lines of the rectifier and the AC inputs of the first and second half-controlled bridge rectifiers to provide AC power to the bridge rectifiers through the inductances; and (e) a controller connected to the switching devices of the first and second half-controlled bridge rectifiers to control the switching thereof.
