摘要： The present invention provides an isolated power supply circuit with a programmable function and a control method thereof. The isolated power supply circuit includes: a transformer circuit, a power switch circuit, a control circuit, and a discharge circuit. The control circuit generates an operation signal and a bleeding signal according to a setting signal. The discharge circuit is coupled to an output node, for generating a discharging current. When the programmable output voltage at the output node switches between different predetermined levels, in a transition period, the bleeding signal adjusts the discharging current to discharge the output node, such that the transition period is shortened.

摘要： An apparatus for controlling a current type inverter including a bridge circuit of bridge-connected self-extinguish elements triggered by pulse width modulation signals. A current is provided for applying a single or plural triggering pulses having a desired pulse width to those self-extinguish elements connected in series with the other self-extinguish elements forming the pairs in the bridge circuit and which other self-extinguish elements are turned on by the pulse width modulation signals. By the above manner of control, the current type inverter can generate output currents of sinusoidal waveform, and the value of the output currents can be controlled over a very wide range.

Two modes of operation described in detail are a chopping mode in which chopping is controlled independently in two adjacent phases at the same time, and a single pulse mode with free-wheeling.

摘要： In order to energize a load with an output current generally conforming to a control voltage, trains of firing pulses are alternately applied during respective conduction intervals of a recurrence period to a pair of main thyristors connected to opposite terminals of a balanced power supply which may be a DC source. The main thyristors are quenched, at the ends of their respective conduction intervals, by ancillary thyristors which lie in series with a resonant circuit including a commutating capacitor and alternately receive firing pulses in continuous succession in order to keep that capacitor operatively connected at all times to one or the other terminal of the power supply. The transmission of firing pulses to the several thyristors is timed by a logic circuit under the control of a comparator to which the control voltage is fed together with a sawtooth voltage establishing the aforementioned recurrence period.

摘要： Switching waveform generator for pulse width modulation triggering of static inverters producing variable frequency output. The number of chops per half-cycle of output fundamental frequency is decreased as fundamental frequency is increased so as to keep the switching frequency of the inverter within the capabilities of the power switching devices used while obtaining maximum harmonic suppression. The chop number is changed between sequential frequency ranges. In a preferred form the chop width is continuously varied as output frequency is varied to decrease output amplitude with decreasing frequency to enable constant torque operation of an induction motor load.

摘要： There are arranged an oscillator for generating a first pulse signal on which the AC output frequency of the inverter is based, a delay circuit for generating a second pulse signal delayed for a predetermined period of time from the first pulse signal, and a ring counter for generating responsive to the second pulse signal a phase reference signal corresponding in phase to the AC output of the inverter. An ON pulse is generated responsive to the second pulse and the phase reference signal and an OFF pulse responsive to the first pulse and the phase reference signal. A negative bias signal is generated following the OFF pulse. At the time of operation stop the negative bias signal following the ON and OFF pulses is applied to GTO thyristors simultaneously.
