Electronic enterprises [india] provides hybrid pulse width modulation [pwm] switching amplifiers from apex microtechnology. In order to use in thousands of industrial and military applications ,more than several models of pwm switching amplifiers and motion controllers are available. These amplifiers have shown the way to deliver far more power [hundreds or thousands of watts to the load] in many applications at a lower cost than comparable linear amplifiers. The switching amplifiers provide solutions to high power drives, which could otherwise require in inordinate amount of heat sinking hardware. Generally hybrid pwm speeds up the design process and greatly enhances fault tolerance by offering protection circuits which is simply not possible in a discrete implementation. These features can make an electronic motion control solution feasible where a hydraulic solution may have previously been the only practical alternative. The pwm amplifiers work with switching frequency up to 500 khz and 5 kw power with continuous current up to 30 a into a load.
