Notice:The user manual is in Chinese, and we cannot provide an English version. If you have difficulty reading Chinese, please do not buy this product.
EGP1000W inverter power board is a supporting EG8010SPWM chip and EGS002
Sine-wave inverter driver board dedicated power backplane, and applies to the following 3KVA inverter unit
EGP1000W inverter power board has two operating modes: front stage after the high-frequency DC-DC step-
up transformer high voltage DC input power connector directly to the power inverter board output mode
(high frequency mode); direct input low voltage DC to board the power inverter output voltage AC power
connector after boosting output frequency transformer high-voltage AC (frequency mode). Users can select
the operating mode according to the needs and power devices, and through the regulator AC output voltage
adjustment potentiometer. (Note: Inductor LI Size About 2 mh. Inductor iron kernel: Iron silicon aluminum)

EGP1000W inverter power board for two modes of operation:
1, high-frequency modes: pre-first by a high-frequency DC-DC step-up transformer to the DC high voltage,
and then connect this to the power of the DC high voltage power supply interface board; (schematic diagram
as below picture shows.); Max output frequency for high frequency mode is:23.4KHZ.
2, the frequency modes: direct input low voltage DC to power board power connector, low voltage AC
inverter output, then boost output by frequency transformer high-voltage AC.

EGP1000W inverter power board by a EGS002 sine wave inverter driver board dedicated interfaces, eight
power tube twenty-two composed of parallel full-bridge power unit, LC filter unit, low-voltage power
management unit, voltage and current feedback unit and the temperature detection unit. Board can be
installed heatsink and fan, and can open or close the cooling fan on the fan control function EGS002
according to temperature.

Board Power Interface:
EGP1000W inverter power board has three power interface: Power Power Interface (P3, P4), drive power connector (P5)
and fan power connector (P 1).
EGP1000W inverter power board has three power interface: Power Power Interface (P3, P4), drive power connector (P5)
and fan power connector (P 1).
1, the power supply (P3, P4)
Mainly full-bridge inverter power supply provides power to the inverter output. Working at high frequency mode, the
power supply for a group of high-voltage DC power supply, to the inverter output AC 220V, the input DC power voltage
must be between 330V一450V, high-frequency transformer high-voltage DC power supply can be DC-DC I pressure to
get. Operating in frequency mode, the power supply for a group of low-voltage DC power supply voltage is usually not
more than 60V, can be battery or other DC power supply.
2, the driving power supply（P5）
Mainly for SPWM control circuit and power tube drive circuit power supply, input voltage is+12V. Operating in the
high frequency mode, since the power supply voltage of 330V or more usually, it is necessary to use another set of + 12V
DC power supply separately for the driving circuits. Operating in frequency mode, the power supply voltage is usually not
more than 60V, the power supply can be used to drive circuitry can also add a group+12V DC power supply through a
separate circuit for driving the buck circuit board.
3, fan power(P1)
Primarily to provide power for cooling fans, due to the cooling fan operating voltage, generally requires an external power
supply fan, operating in frequency mode, but also by the power supply configuration juniper JP2 choice for cooling fan
pover.

4, AC output interface(P8, P9)
Board P8, P9 connector for AC output interface. When the high-frequency mode, the board (L3, C 13) provides 220V pure
sine wave output directly after the LC filter. When the frequency mode, the board LC filter circuit(L1, C13) may be
omitted, with a thick copper wire filter inductor L1 shorted filter capacitor C13 is not welded, SPWM output wavefonn
after the plug-frequency transformer and output filter capacitor 220V sine wave. Refer to section "4.3 frequency mode."
5, power frequency voltage feedback interface(P6, P7)
P6 board. P7 interface for frequency voltage feedback interface, is used only when frequency mode.
