摘要： The present invention relates to voltage converters and especially to a control circuit with an input from the voltage converter output and arranged to control the voltage level on the voltage converter output. The problem addressed relates to the situation when there is a pre-bias voltage on the converter output at the moment it is switched on. The object of the control circuit is to increase the voltage on the converter output fast and avoiding any drain of voltage or current from the output at the start up sequence. This is performed by a comparator in the control circuit that is arranged to compare the reference voltage with a division of the output voltage and if the reference voltage is lower that the divided output voltage the reference voltage is increased at the comparator output. The comparator circuit includes an OP-amplifier.

The reverse current module monitors a first voltage that is based on an output voltage of the output inductance and a second voltage that is based on an input voltage of the output inductance. The reverse current module anticipates a reverse current condition based on the first and second voltages.

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.
