9.1 INTRODUCTION

The electronic devices such as p-n junction semiconductor diode, bipolar junction transistor or field-effect transistor are the devices that can handle very low powers and are not suitable to be operated at high powers of the order of kilowatts or above. To control these high powers, special electronic devices are required. ...
