摘要： A semiconductor switch circuit is connected to a primary winding of a transformer having a secondary winding connected to a load. The semiconductor switch circuit has switches controlled by PWM to provide a controlled constant current. In the inventive inverter, constant current control is performed by PWM operation of the switches of the semiconductor switch circuit. The inverter cuts off electricity to the control circuit when putting the control circuit into a standby state if a run-stop signal gains a logical stop-state. At the same time as the run-stop signal gaining the stop-state, switch drive signals enabling the switches of the semiconductor switch circuit are turned off. Thus, over-current can be prevented from flowing in the load when the control circuit is put into the standby state.

摘要： A start-up circuit with lower current requirements than a conventional start-up circuit is disclosed. The start-up circuit may achieve lower current requirements by reducing the current of the start-up circuit to approximately zero when the bandgap circuit reaches a predetermined value. For example, the start-up circuit may peak at a current of 3.3 micro Amps in order to ensure that the bandgap circuit reaches the predetermined voltage. Thereafter, the current for the start-up circuit may be reduced to approximately zero once the bandgap circuit no longer requires the start-up circuit.

摘要： A power supply circuit includes a control circuit which outputs a control signal when an in-rush current flows and a power-supply-resistance control circuit which supplies a current to a capacitive load. The power-supply-resistance control circuit, provided in the current path between a power supply and the capacitive load, increases the resistance of the current path in response to the control signal and reduces the resistance of the current path in response to a stop page of the control signal, whereby the control signal is output or stopped so that the in-rush current is suppressed to a value smaller than or equal to a given value.

摘要： A dc-ac converter capable of supplying a finely regulated ac drive voltage to a load is provided. For this purpose, the converter includes, in a primary winding of a transformer, a full-bridge or half-bridge type semiconductor switch circuit whose switches can be controlled by pulse-width modulation. Transformer has a secondary winding for connection with a load. Based on PWM signals and by use of adequate switching logics for controlling multiple semiconductor switches, sophisticated control including zero-current switching and penetrating current prevention can be effected. Moreover, by means of regulated burst control of the ratio of on-duty period to off-duty period together with pulse-width modulation control, power supplied to the load can be regulated over a wide range beyond the limits of control obtained by the pulse-width modulation.

摘要： Switches (such as FET's and other devices) are often used in circuits to generate an AC signal from a DC supply input. There are times when the supplied DC voltage is greater than desired for the ratings of the switches that can or must be used. There are also times when there may be voltage surges or other transient high voltage conditions for which it is desired to have greater margin between the voltage applied and the switch ratings. The circuit described applies across any of the switches a maximum of one half of the supplied DC voltage. The circuit may also be operated in a linear mode for use with analog signals.
