The bridge type DC-DC converter may include half bridge, full bridge or BUCK. The method includes simultaneously controlling the boost and DC-DC converters by using PFWM. In one aspect, the bridge type DC-DC output voltage or current or power is sensed to obtain duty of PWM for driving switching components. The duty is used to adjust DC-DC output voltage or current or power. In the other aspect, the boost converter's operating parameter is sensed to obtain a frequency of PFM for driving switching components. The frequency is used to adjust boost output voltage. The above frequency and duty are combined into at least a pair of complementary PFWM driving signals, to directly or indirectly drive switching components of the combination power supply of boost converter and bridge type DC-DC converter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"PFWM control method for power supply","description":"A PFWM control method for a combination power supply of boost converter and bridge type DC-DC converter is disclosed.
