This invention provides a charge-type control circuit, control system, and control method for a three-arm resonant topology. The charge-type control circuit controls a three-arm resonant topology circuit to perform six-step commutation. A circuit output feedback module collects the output electrical signal of the three-arm resonant topology circuit and processes the signal to obtain a feedback result. An integral comparison module collects the primary resonant signal, calculates the integral result, compares the integral result with the feedback result, and outputs a pulse trigger signal based on the comparison result. A drive generation module outputs a frequency adjustment signal to the three-arm resonant topology circuit based on the pulse trigger signal. The frequency adjustment signal controls the three-arm resonant topology circuit to perform six-step commutation. By triggering the state flip of the switching transistor when the integral calculation result reaches a preset threshold, inconsistencies in the parameters of the resonant components between the bridge arms that lead to uneven current flow are avoided, thus improving the device's lifespan and reliability.

This invention belongs to the field of soundproof glass processing technology, specifically relating to a multi-layer laminated soundproof glass and its lamination process. The multi-layer laminated soundproof glass is composed of multiple layers of glass sheets alternately laminated with sound-insulating films. The thickness of the glass sheets gradually increases from the outside to the inside, with a thickness difference of at least 1 mm between adjacent glass sheets. The sound-insulating film gradually increases in damping from the outside to the inside, forming a gradient damping structure. For 3-layer or 4-layer glass structures, materials such as PVB film, SGP ionic interlayer film, and modified butyl rubber sound-insulating film with corresponding layer numbers are selected. The lamination process employs segmented temperature and pressure controlled curing and stepped gradient slow cooling. This invention effectively staggers the resonance peaks of each glass layer, solving defects such as residual bubbles, interlayer misalignment, and stress cracking in existing processes. The resulting product has a weighted sound insulation Rw of 38-45 dB, a yield rate >98%, and is controllable, highly versatile, and suitable for industrial mass production in high-end buildings and quiet environments.
