• ### Large scale integration in DC drive controller

Publication Year: 1992, Page(s):1/1 - 1/4
| | PDF (276 KB)

Custom silicon has become an accepted means of carrying out much of the power device control in AC drives since, very often, it is the only economical way of synthesizing complex pulse output patterns. The power devices in a DC drive require relatively simple control sequences but it is possible to clearly demonstrate that digital control using a moderate level of logic integration can be economic...

Reductions in the size of power electronic equipment brought about by improved devices and packaging technology can now be matched even at moderate sales volumes by smaller control circuits employing ASICs. A digital ASIC is used to replace a microprocessor in a sinusoidal PWM system. An encoded look-up table is used to greatly reduce the silicon area required and hence reduce costs. A mixed techn...

| | PDF (200 KB)

The authors describe the operation and commissioning of a novel control strategy enabled by the use of a pair of digital ASIC devices. The speed of operation of such devices allows the control of the induction motor drive power devices to within 1° of the zero crossing of the 50 Hz waveform. In addition a reduction in size of the control equipment by 10:1 was achieved. The inclusion of a synch... View full abstract»

• ### Application experience in switched reluctance motor control using ASIC technology

Publication Year: 1992, Page(s):5/1 - 5/4
| | PDF (168 KB)

The switched reluctance (SR) motor offers the prospect of a low-cost fully controllable brushless motor drive. It requires a low-cost controller which will provide all the necessary control functions for variable speed operation. The LMB 1008 mixed analogue/digital ASIC was designed as a minimum silicon solution to three phase switched reluctance motor control. The authors describe the capabilitie... View full abstract»

• ### Driving high side' power MOSFETs and IGBTs at high voltage using ASICs

Publication Year: 1992, Page(s):3/1 - 3/4

| | PDF (192 KB)

The authors have presented an outline design of a gate drive for a `high side' MOSFET switching at high voltage. Galvanic isolation and switching have been achieved using a pulse transformer with only two components on the secondary (gate) side. The additional complexity of the circuitry on the primary side has been integrated into an ASIC. The logic sequence was designed to provide integrity of t... View full abstract»
