Technical Examples

The solid state switching section of a high frequency PWM switching power supply may encounter problems in accurately regulating output power when the requested output power is above a threshold level, the threshold level typically being a high level approaching one hundred percent of the power of the sinusoidal AC power source. Below the threshold level, the power supply is operated in a full PWM mode to regulate the output power level. Above the threshold level, the power supply is operated in a full on, continuously conducting mode in a central part of the half cycles of the AC supply. Outside of this central portion, the power supply is operated in the in the PWM mode, using a duty cycle within the capability of the solid state switching section. The output power level is regulated by varying the duration of the central full on portion of the half cycle. A similar control method is used for reducing heat generated by the solid state switching section of the power supply.
