The project is built using \u003c\/span\u003e\u003cstrong\u003eFSB50550AT\u003c\/strong\u003e\u003cspan\u003e IPM chip. This compact and reliable inverter project is ideal for small power motors such as fans and pumps. An H-bridge configuration can also be created for low current high-voltage brushed DC motors. The Inverter board supports a load up to \u003c\/span\u003e\u003cstrong\u003e2A\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 C3, C4, and C5 value is \u003c\/span\u003e\u003cstrong\u003e1uF\u003c\/strong\u003e\u003cspan\u003e. Resistor R4, R6, R7, R11, R15, R16 and capacitor C9, C10, C11, C12, C16, C17 prevent improper signal due to surge-noise. The logic supply is protected with a \u003c\/span\u003e\u003cstrong\u003e20V Zener\u003c\/strong\u003e\u003cspan\u003e diode, which prevents surges under severe conditions. Comparator \u003c\/span\u003e\u003cstrong\u003eU2A\u003c\/strong\u003e\u003cspan\u003e provides low output when an overcurrent condition occurs, it measures the current across shunt resistor R13, and normal output is high. Comparator \u003c\/span\u003e\u003cstrong\u003eU2B\u003c\/strong\u003e\u003cspan\u003e is provided for over-temperature detection, the output of U2B is high when IPM temperature is below \u003c\/span\u003e\u003cstrong\u003e80 degrees C\u003c\/strong\u003e\u003cspan\u003e, and goes low when the temperature reaches the threshold. A heatsink is a must for full load current, thus 2 mounting holes are provided throughout the PCB to mount the heatsink as shown in the Figure below. Silicone thermal compound, also called thermal grease, should be applied between the heat sink and the flat surface of the IPM to fill microscopic air gaps due to imperfect flatness that ultimately reduces the contact thermal resistance. The IPM module should be soldered first. Please take care of excessive torque that may bend the PCB.\u003c\/span\u003e\u003c\/p\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":47193554583724,"sku":"M115","price":40.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/M115A.jpg?v=1789219392","url":"https:\/\/dotfry.com\/products\/3-phase-ipm-module-for-small-power-ac-motor","provider":"dotfry","version":"1.0","type":"link"}
