This is a 3-Phase Inverter Driver project designed for Low Power AC Motor. The FSB50450AS chip is the heart of the project. A compact 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 project supports loads up to 1.5A. The DC power supply voltage is up to 400V DC. The project operates with 6 x PWM signals. Parameters for bootstrap circuit elements are dependent on the PWM algorithm. For 15 kHz switching frequency, Bootstrap capacitors C1, C2, and C3 value is 1uF. 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 – LMV7239 and shunt resistor R5. The output of LMV7239 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 IPM chip. Heatsink is a must for this IPM module. Adhesive material with high thermal conductivity, such as Loctite 384, can be used to fix the heat sink on the top surface of the chip. Refer to the heatsink installation diagram.

This is Arduino compatible hardware that can control a single DC motor speed, direction, and brake using an RF remote control. The project is based on an ATMEGA328 microcontroller, H-Bridge DC motor driver chip LM18201, NRF24L01 RF module, 5V Regulator, 3.3V regulator and other components. This board can drive a DC Motor up to 24V DC with a load current up to 3A. Arduino pin configuration details are provided below, the user may write their own code and use this hardware. The  ATMEGA328 is the heart of the project, the LMD18201 chip drives the motor, LM317-ADJ provides 5V to the microcontroller, LM1117 3.3V regulator power the 3.3V to NRF24L01.

This tiny board is designed to drive a bidirectional DC brushed motor of large current. DC supply is up to 50V DC. A3941 gate driver IC and 4X N Channel Mosfet IRLR024 used as H-Bridge. The project can handle a load of up to 10A. Screw terminals are provided to connect the load and load supply, and 9 Pin header connector is provided for easy interface with the microcontroller. An on board, shunt resistor provides current feedback.

The A3941 is a full-bridge controller for use with external N-channel power MOSFETs and is specifically designed for automotive applications with high-power inductive loads, such as brush DC motors. A unique charge pump regulator provides full (>10 V) gate drive for battery voltages down to 7 V and allows the A3941 to operate with a reduced gate drive, down to 5.5 V. A bootstrap capacitor is used to provide the above-battery supply voltage required for N-channel MOSFETs. An internal charge pump for the high-side drive allows DC (100% duty cycle) operation.

There is an onboard potentiometer to control the RC servo up to 180 degrees. It allows you to record the movement of one servo, a few seconds in duration. Servo movement can be mimicked using the onboard potentiometer. Servo movement data is stored onboard the EEPROM memory chip. The project is Arduino compatible and can be modified to work as a data logger and other applications that require EEPROM and SD Card data logs.

A programmable pulse generator is a very useful tool for stepper, BLDC, and AC servo drivers. Various stepper and servo drivers work with step and direction inputs. This project is the right solution to drive such drivers since it can provide a high-frequency output which is important for most AC servo drivers. The project provides a jitter-free high-frequency pulse, direction, and enable signal. The output frequency can be configured up to 12 MHz since the project is Arduino-compatible. All outputs are open collector types (5V). 2 x tactile switches are provided to set the direction and enable. An onboard trimmer potentiometer is provided to adjust the step frequency.

This board enables low power consumption by direct PWM or PWM constant current control. Built-in protection circuits in this IC are present. It is possible to output an abnormal detection signal for Wired-OR that notifies each protection circuit operation, and this contributes to the high reliability of this board.

The project presented here is a low-cost solution to control high power brushed DC motor speed and direction. Traditional DC motor controllers are based on solid-state circuitry known as H-Bridge. Here we have made an H-bridge configuration using high current 2 x relays which can handle high voltage as well as high current. Additional MOSFETs are used to control the speed of motor. These MOSFETs can be removed in case of only direction control required, short the Drain and source pin of MOSFETs. The project requires 3 control input signals, all inputs are optically isolated to prevent noise and high voltage going in to logic circuitry. A large-size heatsink is a must on MOSFET.
