inverter circuit SG3524 smps control IC on the Board already sold in the market a lot of offline UPS device that is being used to integrate. İnverter circuit with protection against overheating the MOSFETs PTC provided 70 as system closes the control circuit is also active in 40 degrees çivarında fan fan cooling. Also, when the battery voltage is low (10.5 v border) are truncated with a relay system to feed.
Measurement of output voltage True RMS measuring instrument the author or use the oscilloscope to measure the correct exit non-RMS, True, that suggests the voltage measurement cannot be appliances from voltage 170-270v Mohammed kublör opto isolation is provided with circuit and also you can see the promer and secondary from independent. Commissioning of the schema, and pcb (eagle) drawings of materials.
Attention inverter circuit produces high voltage capacitor connection Observe caution + – If you connect the high voltage polarity may be large explosions before running the insured Power Line circuit, protective goggles
PR1 is connected to AC 230v CNY17 220k potentiometer output with adjustable output voltage
