Title: Dc/ac power converter
Inventor: YASUOKA IKUO
IPC: H02M1/12
Filed: 1979-02-21
Abstract: PURPOSE: To provide an automotive power converter which has small size, light weight and stability in operation by utilizing an impulse current commutation system having reverse blocking thyristors at commutation arm and reverse conducting thyristors at main arms.  
     CONSTITUTION: A commutation thyristors S 3  and main thyristors SU, SV, SX and SY are gate controlled so that the output voltage of an inverter circuit 3 may become alternating rectangular waveform voltage. During on period of the thyristor S 3  its control angle α is represented by "60°-α". In case that a line voltage is raised, the control angle α is increased to shorten the on period of the thyristor S 3  to produce a rectangular waveform voltage modulated by two pulses like one pulse during 0∼ 60° of positive side half cycle period of 0∼180° and another one pulse during 60∼ 120° and similar rectangular waveform voltage even in the negative side half cycle period of 180°∼360°. Since this impulse current conversion system conducts two pulse modulation only with the polarity inversion of a commutation capacitor, it can readily stabilize the operation of the power converter.

Abstract: PROBLEM TO BE SOLVED: To cut a recording sheet automatically by fixing a recording sheet cutter on one side in the sheet feeding direction of a carriage traveling in the main scanning direction for recording such that it can be operated to take a position spaced apart from a cutting position. SOLUTION: At the time of normal recording, a cutter 4 is urged by a spring 5 to be held at a position separated from a recording sheet S and idling as a carriage 1 travels.
