Title: Constant sampling type pwm device for sine wave input- output single-phase voltage doubler ac-dc converting circuit
Inventor: SHODA EISUKE
IPC: H02M7/48
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To perform PWM control on a single-phase voltage doubler AC-DC converting circuit with a simple constitution by selecting the gate command of each principle element of the converting circuit at a prescribed control delay time based on the directions of error functions obtained at every sampling time. SOLUTION: A pulse width modulator 1 operates upon receiving a sampling pulse from a pulse generator 2 and outputs gate commands to two principal elements U and X at the time (tn+tc) after a control delay time Tc (Tc<=Ts) by reading the value of the error function Δ(tn) between a system current i(tn) and 8 target function j(tn) at every sampling time tn.  When the gate commands are set in such a way that, when Δ(tn)<=0, the element U is turned off and the element X is turned on and, when Δ(tn)>0, the element U is turned on and the element X is turned off, the system current i(tn) can be increased by turning on the element X, because the current i(tn) is smaller than the target function j(tn) when the error function Δ(tn) is Δ(tn)<=0, and the current i(tn) can be reduced by turning on the element U, because the current i(tn) is larger than the function j(tn) when the error function Δ(tn) is Δ(tn)>0.

Title: Switching signal adjuster for semiconductor switch
Inventor: SUGITA TAKANORI
IPC: H02M7/537
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To uniformize voltage shares of IGBTs multiply series connected, and to prevent breakage of devices. SOLUTION: A series multiple switch 30 is constituted by multiply series connecting a plurality of IGBTs 41, 42...4n. To each IGBT, a gate signal G is inputted through a time-delay generating circuit 51, 52...5n, and the voltage between the input terminal and the output terminal of each IGBT is measured by a voltage measuring circuit 71, 72...7n. The earlier the turn-off timing of a device is, the higher the value of its measured voltage becomes. A time-delay controller 10 delays the delay time of a time-delay generating circuit arranged corresponding to a device whose measured voltage is high. Consequently, to a device which turned off earlier last time, the gate signal G is delayed longer than last time and inputted, and the turn-off timing of that device delays, and a measured voltage (shared voltage) of that device lowers.
