Title: Converter connection with balancing circuit
Inventor: GUNNAA ASUPURANDO
IPC: H02M7/217
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To connect a converter to an AC voltage network without using an intermediate individual winding transformer by a method, wherein a control signal is generated and supplied to a gate turn-off semiconductor valve, so as to make the time average of a voltage at a junction point equal to a voltage between two terminals of a capacitor. SOLUTION: A control signal -CS, by which one of the thyristors of valves V7 and V8 is electrically conducting for a time of half the period, while the respective thyristors are electrically conducting to make the time average of a voltage at a junction point J equal to the average of the terminal voltages of corresponding capacitors, i.e., zero. If a voltage +Ud is supplied to the neutral electrode of a single electrode power network, symmetrical DC voltages +UC and -UC are respectively supplied to the DC voltage terminals of a converter VC, and the voltages +UC and -UC are equal to +Ud/2 and -Ud/2. Therefore, the converter can be connected to an AC voltage network, without the use of an intermediate individual winding transformer.

Filed: 1989-08-23
Abstract: PURPOSE:To easily obtain synchronization with an external device equipped with arbitrary communication speed by calculating values concerning accumulation time and communication speed and outputting a mode signal and a sub scanning period signal. CONSTITUTION:Based on signals to be outputted from a first signal holding means 8 to hold the accumulation time and a second signal holding means 9 to hold the value concerning the communication speed when a picture signal is outputted to the external device, an arithmetic means 7 judges whether the speed of communication with the external device is higher or lower than the signal output speed of a picture reader.
