{"product_id":"3-phase-inverter-for-low-power-ac-motor","title":"3 Phase Inverter for Low Power AC Motor","description":"\u003cp\u003e\u003cspan\u003eThis is a \u003c\/span\u003e\u003cstrong\u003e3-Phase Inverter Driver\u003c\/strong\u003e\u003cspan\u003e project designed for Low Power AC Motor. The \u003c\/span\u003e\u003cstrong\u003eFSB50450AS\u003c\/strong\u003e\u003cspan\u003e chip is the heart of the project. A compact inverter project is ideal for small power motors such as fans and pumps. An \u003c\/span\u003e\u003cstrong\u003eH-bridge\u003c\/strong\u003e\u003cspan\u003e configuration can also be created for low-current high-voltage brushed DC motors. The Inverter project supports loads up to\u003c\/span\u003e\u003cstrong\u003e\u003cspan\u003e \u003c\/span\u003e1.5A\u003c\/strong\u003e\u003cspan\u003e. The DC power supply voltage is up to \u003c\/span\u003e\u003cstrong\u003e400V DC\u003c\/strong\u003e\u003cspan\u003e. The project operates with 6 x PWM signals. Parameters for bootstrap circuit elements are dependent on the PWM algorithm. For \u003c\/span\u003e\u003cstrong\u003e15 kHz\u003c\/strong\u003e\u003cspan\u003e switching frequency, Bootstrap capacitors C1, C2, and C3 value is \u003c\/span\u003e\u003cstrong\u003e1uF\u003c\/strong\u003e\u003cspan\u003e. Resistor R1, R2, R3, R4, R6, R7 and capacitor C4, C5, C6, C7, C8, C9 prevent improper signal due to surge-noise. Over-current or fault detection circuit is created using comparator CN5 – \u003c\/span\u003e\u003cstrong\u003eLMV7239\u003c\/strong\u003e\u003cspan\u003e and shunt resistor R5. The output of \u003c\/span\u003e\u003cstrong\u003eLMV7239\u003c\/strong\u003e\u003cspan\u003e is normally high and goes low when an over-current condition occurs. So, the CS pin goes low when the current goes above the threshold level. ATS pin is provided to monitor the temperature of the \u003c\/span\u003e\u003cstrong\u003eIPM\u003c\/strong\u003e\u003cspan\u003e chip. Heatsink is a must for this IPM module. Adhesive material with high thermal conductivity, such as \u003c\/span\u003e\u003cstrong\u003eLoctite 384\u003c\/strong\u003e\u003cspan\u003e, can be used to fix the heat sink on the top surface of the chip.
