Filed: 1981-11-13
Abstract: PURPOSE:To reduce the harmonic wave of a converter which controls the opening and closing of a switching element with a specific frequency by inserting a filter between a converter bridge and a polyphase AC power source. CONSTITUTION:A filter 16 is inserted between a converter bridge 15 and a 3- phase AC power source 1. When the filter 16 is thus inserted between the bridge 15 and th power source 1 to reduce the harmonic wave in this case, the harmonic wave in the vicinity of the resonance frequency of the element forming the filter becomes large. Accordingly, the set of the resonance frequency to 6n+ or -1 times of the power source frequency contained in the AC side current is avoided so as not to increase the harmonic wave of the frequency of 6n+ or -1 times of the power source frequency, thereby reducing the harmonic wave.

Abstract: PROBLEM TO BE SOLVED: To realize a steep doping change at the time of successively growing layers of different impurity density by making the number of open molecular beam cells different when adjacent layers of different impurity are formed by using plural molecular beam cells for supply of material to the same material of the desired layer. SOLUTION: Though each one molecular beam cell is used for As and Be cells, a p-GaA layer 19a is grown by setting Ga1 cell and Ga2 cell and a p+- GaAs layer 19b by Ga1 cell in such a way that each cell generates molecular beam. Accordingly, two Ga cells are used. For the layer 19b, since the molecular beam amount of Ga is a half of that of the layer 19a, the molecular beam amount of the Be cell is constant but the doping density can be twice. Furthermore, at the time of starting the layer 19b, since the doping density is changed only by closing the Ga2 cell, there is no flux transient phenomenon and a very steep change in doping density can be obtained.
