Controller/inverter chipset optimises PWM drives
A new motor controller and inverter chipset aims to significantly reduce the acoustic and electrical noise of PWM motor drives as well as improving efficiency and minimising component count
Toshiba has a new motor controller and inverter chipset it claims will significantly reduce the acoustic and electrical noise of PWM motor drive applications as well as improving efficiency levels and minimising component count. Toshiba's TB6551F three-phase brushless motor controller provides a full sinewave PWM output without the need for an external microcontroller, and the new TPD4103AK is a single-chip 500V inverter.

High-speed CMOS 2bit dual supply bus switches provide an interface between two nodes at differing voltage levels
Together the devices deliver a compact, two-chip solution for the high-efficiency, low-noise driving of three-phase brushless DC motors or AC induction motors with ratings of up to 400V.
Electrical and acoustic noise can be introduced into PWM motor control applications by the rapid switching of motor coil current.
Traditionally this problem has been addressed using an external microcontroller and software that manipulates the PWM signal to generate a sinusoidal motor coil current waveform.

Now, however, the built-in sinewave function offered by the TB6551F provides an integrated hardware solution.
Toshiba's TPD4103AK chip inverter IC is rated for 500V/1A operation and switching frequencies up to 25kHz and accepts the sine wave input directly from the TB6551F IC.
As a result, the two ICs can be used to quickly and easily implement a 'silent' motor drive with all of the high-efficiency and low-power dissipation benefits provided by sinus modulated PWM control.
The TB6551F features a built-in triangular wave generator with a carrier frequency of fosc/252Hz.
An integrated lead angle control function allows the designer to move the lead angle between 0 and 58 degrees in 32 separate steps.
The ability to optimise lead angle electronically, rather than using conventional mechanical adjustment, allows designers to fine tune their application for optimum efficiency, facilitating the use of lower cost, lower power and smaller motors.
A dead-time function can be set for 2.6 or 3.8us to ensure safe operation of the power IGBTs in a push-pull configuration.
Additional onboard functionality includes overcurrent protection.
Functionality built in to the TPD4103AK inverter includes protection against overtemperature and undervoltage conditions.
