Abstract: An apparatus utilizing additive interleaved switchmode (PWM) power conversion stages, having minimal or no output filter, to achieve high bandwidth or even ideally instantaneous power conversion. The additive process may involve voltage stacking of isolated PWM converters, which are interleaved in time, or may involve a single input power supply and inductively combining output currents of PWM power converters interleaved in time, with either additive circuit having minimal or no output filtering. This circuit may overcome limitations for the frequency of feedback control loops once thought to be physical limitations, such as, fundamental switching frequency, output filter delay and the Nyquist criteria.

Abstract: A high power radio frequency power method of amplifications described in which a variety of amplifiers (60 & 86) may be used to reduce the stress any one amplifier experiences. The power leads (64 & 65) may be arranged in a series to power each amplifier at potentials which are lower than the total potential. Outputs (63) may then be connected in a parallel fashion to combine the power output by the system. A variety of unique stabilization, drive, division, combination, and supply configurations are presented as well as the possibility of utilization and adaptation of the designs for a plasma processing system. An aspect of tiered combining is included such as may be especially appropriate for larger numbers of devices which may include switchmode amplifiers and the like.

Abstract: Disclosed are both methods and a circuit to achieve powers of many kilowatts in radio frequency amplification using a switch mode amplifier in a new class of operation. In operation the invention utilizes internal switch characteristics. Methods create a substantial voltage step at the end of a response time period which allows greater output power without increasing the maximum switch voltage, reduces the maximum switch voltage for the same power, and which permits reduction of the stress on the switch element. Utilization of internal varactor capacitance avoids undesirable circulating currents and avoids the effects of lead inductance. The design allows use of less expensive components and high voltage switches not manufactured for radio frequency applications by preferring a substantial internal capacitance to establish maximum power. Other components of the network circuitry are also coordinated with the internal varactor capacitance.
