LED keen high . Luminous effectiveness Advanced strengths . When it is used in the inverter control cabinet , because the inverter is converted voltage with a frequency of the PWM pulse width modulation method ,power inverter, the main circuit current contains more high harmonics . This is demonstrated by the coupling between the wires . The LED will also issue a shining light, damage the accuracy of the guidance signal voltage . The
solution measures in LED signal components at both ends and a capacitor coupling the drive over the high-frequency high internal resistance of the current bypass ,Grid tie inverter. LED not should not emitting sparkle .
the
capacitance with pressure value their own to one thermal power plant for heat pump 100kW inverter control cabinet using a capacitor value 0047μF withstand voltage value is DC 630V polyester capacitors . This cabinet dominated circuit voltage signal lamp voltage AC220V ,www.12vgridtiepowerinverters.com.
due to the frequency of the circuit to power frequency 50Hz . So use the less expensive DC capacitor is not the problem . If the signal lamp components voltage is . AC380V, DC withstand voltage of the capacitor should progress to lkV. Smaller capacity inverter , power capacity can also be reduced accordingly .
this manner can also be used to the rest of the similar high - frequency induction current instigation circuit . http://www.gridtieinverter.de/
