DEVICE AND. iNVERTER OPERATION

- voltage converter IPC 70V / 13,8V 15A formed on the principle of two-stroke power converting DC voltage into high frequency pulse voltage, which is then transformed to a higher voltage, followed by rectification and filtering
- control push-pull inverter is controlled in a pulse width modulation (PWM) of signals from the PWM controller that adjusts output voltage by changing the pulse duty ratio
-. Stabilization of the output voltage and current is achieved a negative feedback circuit consisting of formers signals proportional output parameters which arrive at the input of the PWM controller, which compares with a reference voltage and changing the duty ratio of the pulses in the direction of recovery deviated parameter values ​​
-. Galvanic separation of the output voltage from the inverter circuit board is performed by mains power transformer and optoelectronic devices
-. In order to reduce the radiation level of industrial interference on the input supply rail network and the output of the voltage converter circuit mounted suppression filters. In addition, it has adopted a special circuit design and design measures that minimize RF emission levels
-. In order to reduce the weight and size of the voltage converter to be cooled by a fan. Fan speed is controlled depending on the temperature state of the most heat-power elements, which improves the durability and reliability of the cooling system.
